Welcome
Thank you for purchasing a sonuus Wahoo. Like all sonuus products, the Wahoo is the culmination of ground-breaking innovation and considerable technical expertise. We are delighted that you have chosen to purchase a sonuus Wahoo and we anticipate that it will greatly enhance your music making. This manual is a comprehensive guide to the Wahoo but if you have any questions, we offer attentive customer support via our on-line user forum:
www.sonuus.com/forum
The Wahoo is a dual analogue filter stomp box. It is packed with innovations from the sonuus Research Team.
Analogue signal path with digital control
The Wahoo’s fully analogue signal path is based on vintage synthesizer filters, and gives the warm organic tone that is possible with only analogue electronics. We have combined the analogue signal path with digital control for precision and configurability.
Dual analogue filter design
The Wahoo has two analogue filters, each of which can be configured as low-pass or band-pass and can operate independently in wah pedal, output can be configured to give evolving textures and tonal depths that cannot be achieved with a single filter.
Ground-breaking pitch-tracking effects
The Wahoo uses sonuus’ proven, and highly acclaimed, pitch-tracking technology to create unique pitch-bend and pitch-tracking effects—effects that have never been available before.
LFO
, envelope and pitch-tracking modes. The dual filter
Unique patented InfiniQ pedal sensor
Most wah pedals operate using a potentiometer (a pot) which wears out quickly resulting in the effect becoming scratchy. These also have mechanical couplings which limit fine control and let dirt inside the unit, so compromising reliability.
Some other wah pedals use optical methods which are susceptible to dirt and interference from stage lighting, and these also have mechanical couplings.
For the Wahoo, we designed a brand new type of position sensor, InfiniQ, that allows super-fine precision control with no mechanical couplings. As a result, the pedal control on the Wahoo won’t get scratchy and will never wear out!
For guitar and bass
The Wahoo is designed from the ground up to be perfect for guitar and bass. We know that many musicians play both instruments and don’t want to compromise when an effect is designed for the

higher or lower frequencies of these instrument: the range of the Wahoo parameters can perfectly match guitar and bass, and you can save and switch between instrument-specific set-ups.
Of course, the Wahoo can also be used on other instruments such as keyboards. You don’t need to restrict your creativity to guitar and bass!
Transparent-true-bypass
True-bypass means that the effect is completely switched out of your signal chain when bypassed to preserve the integrity of your guitar/bass signal. This is typically done by mechanical switches but these cause clicks or pops when switching.
For the Wahoo, we designed a silent-switching true-bypass circuit so you get the benefits of true­bypass without the associated switching noise. What’s more: if the power to the Wahoo is interrupted, the unit will automatically switch back to the bypassed state so you don’t lose your instrument’s signal.
Stage-ready
The Wahoo is designed to be ideal for gigging on stage:
Heavy-duty cast aluminium case that will stand up to years of heavy use.
The pedal won’t decide to get scratchy just before a crucial gig!
Variety of power sources: any polarity 9V for maximum convenience, batteries.

Presets
The Wahoo comes ready-to-play with 100 factory presets which include traditional wah effects, touch-wah, bass envelope filters, auto-wah, bubbly funk, vocal sounds and extreme synth-like special effects. Without making any adjustments, the Wahoo is ready to play, straight out of the box.
The 100 factory presets is just the starting place! By tweaking these presets you can explore different sounds and create your own effects—there are 100 user presets where you can store your own set-ups.

Connecting the Wahoo
The simplest way of connecting the Wahoo is between your guitar and amp: connect the output of your guitar to the input (IN) of the Wahoo. Connect the output ( input.
When using other effects in your signal chain, there is no right or wrong effect order — experiment to see what you can do, and be creative.
Typically, time-based effects such as reverb and delay are placed after the Wahoo so that these effects are applied to the Wahoo’s sound.
When using distortion, the effect of connecting this before or after the Wahoo are very different. When distortion is used after the Wahoo, the effect can be quite subtle, and any noise from the Wahoo can be enhanced (particularly with high-gain distortion effects). When distortion is placed before the Wahoo, the Wahoo is able to shape the harmonically-rich signal from the distortion to get more sonic variation. This also has the advantage of not boosting any noise produced by the Wahoo.
You can also connect the Wahoo to the effects loop of your amp: connect the output of your guitar to the input of your amp, then connect the “send” of your amp to the Wahoo IN, and the Wahoo back to the “return” of your amp. Depending on your amp this can give rise to excessive noise if the signal level in the effects loop is too small. If you try this, it is best to set the effects loop level to +4dBu if you have that option.

Powering the Wahoo
The Wahoo can be powered by batteries, by a 9V DC power supply (neither of these is supplied), or by
USB
. Select one of the following:
insert 4 AA batteries (alkaline can be used, but we recommend rechargeable NiMH batteries) into the battery compartment in the base of the Wahoo. WARNING: observe correct polarity!
plug the output of a 9V DC power supply into the port labelled DC on the back of the Wahoo. The 9V DC power supply that you use should be capable of providing 500mA and have a 2·1mm centre pin connector. Note that the Wahoo has been designed so that either polarity (tip-positive or tip-negative) can be used.

Selecting a factory preset
There are 100 factory presets in the Wahoo. They configure the Wahoo into a variety of set-ups, from traditional wah to sonuus’ unique pitch tracking filter effects. A summary of factory presets is at the back of this manual (page 35).
The Wahoo has two modes: Preset Select mode and Preset Edit mode. By default, it is in Preset Select mode and the display alternates between the 3-character preset name and the preset number: either F00 F99 for factory presets 0 to 99 or P00 P99 for user presets 0 to 99.
If the display does not periodically show F/P0099, then to enter preset mode do the following.
Enter Preset Select mode
If the display is not showing a factory or user preset (F00F99 or P00P99), the Wahoo is in Preset Edit mode: exit this mode by pressing and holding the save button for 2s.
Alternatively, slide the Select mode when locked).

Once the Wahoo is in Preset Select mode, select a preset using the  buttons. A single press on either button will increment/decrement the preset number by one. If you press and hold either button, the preset number will increment/decrement in tens.
Top Tip: Envelope effects have been designed for an instrument with a standard output
level. If your instrument has an unusually high or low output the presets may not sound correct— either too responsive or not responsive enough. Use the custom SEn parameter to adjust the sensitivity of your Wahoo (see page 30).

(auto) effects (F40F59) the filters will move on their own, but the footpedal can be used to control their tempo between preset limits. See “Factory presets” on page 35 for a summary of the factory presets.
While you are playing, you may accidentally bump a switch or button which will take you into Preset Edit mode. To prevent this, and stay in Preset Select mode, you can slide the locked position. Alternatively, just re-enter Preset Select mode as described above.

Foot-operated preset selection
Preset selection using the  buttons and the save button was described in “Selecting a factory preset” on page 9. There is an alternative method of preset selection using the footswitch and the footpedal. This has been specially designed to make it easy to change presets when you are gigging. Using this method, you don’t have to bend down and select presets using your hands.
Preset selection using the footswitch and footpedal
Enter preset mode by pressing and holding the footswitch until the footswitch The time you have to hold for has a default value of 2s, however this is a custom parameter that you can change (see “Custom settings” on page 30).
To increase the preset number, put the footpedal in toe down position (the  button flashes to show that the preset number will increase) then tap (press and release) the footswitch the desired number of times until you reach the preset number you want. To decrease the preset number, move the footpedal to heel down position (the  button now flashes) then tap the footswitch until you reach the preset you want.
When you have reached the preset number you want, you can play and even change presets while playing. However, while in preset select mode you can’t enable or bypass the effect: to do this you have to exit preset mode by pressing and holding the footswitch until the footswitch time to enter it.

Preset selection with the footpedal in effect on/off mode
When the footpedal is configured to be in effect on/off mode (setting the custom parameter P.En to o.Lo or o.hi — see “Custom settings” on page 30) the method described above is replaced by another method. In this case, the footpedal is not used and foot-operated preset selection is always active. In addition, the footswitch is no longer used to enable/disable the effect.
Like the method described above, the footswitch is used to increment or decrement the preset (the direction being shown by the flashing of the  or  button on the footswitch (default press time of 2s) will toggle the direction of preset selection.
Note 1: In foot-operated preset selection mode, you can only step through the presets one at a time (not in tens as you can if you use the  and save buttons). We therefore recommend that for a gig, you make sure that you save the presets you want to use close in number to one another.

Setlists
A setlist is simply a list of presets that you want to use in your “set” during a performance. The setlist feature of the Wahoo lets you define which presets you want to use and makes all other presets unavailable. This way you can easily move between your desired presets without getting lost (the Wahoo has a lot of presets!).
To use the setlist feature you must use the Desktop Editor, available free from:
http://software.sonuus.com
There are 6 setlists available (A–F) as well as a built-in demo setlist that you can’t edit. Once you have configured a setlist you can make it active using using the SET parameter; see “Custom settings” on page 30. The setlist doesn’t become active until you lock the Wahoo.
Normally, presets can be selected by matches the preset number. Setlists give you more flexibility, allowing you to choose any program number for any preset (this also selects which program change messages are sent when you select a new preset on the Wahoo; very useful when controlling other effects from the Wahoo).
Setlist are a great way to tailor the Wahoo for your performance without modifying or moving presets. It lets you focus on your performance, knowing that the sounds you need are available when you need them.

increased, the filter sound begins to distort and add pleasing harmonics to the signal. Turn the drive down for the cleanest sound, but if the drive is too low the signal will become noisy. Turn the drive up for lower noise, and warmer sounds: but if it is turned up too high the sound will become fuzzy, which can itself be a desirable effect.

LEVEL
output (out). Typically you adjust the output level so there is a good balance between the
original sound (when the effect is bypassed) and the effected sound. It is possible to increase the output level to boost the signal beyond the level of the original instrument level which can be useful, for example, to overdrive the input stage of a valve amplifier. Note that at high output settings, the output stage will start to soft-saturate. This lets you achieve louder sounds without worrying about unpleasant clipping, regardless of how hard you play.
LEVEL
output (thr). Some presets, depending on the resonant filter setup (see the next section for
a discussion on filters), have an audible output with no input signal. If you want to remove this, you can do so by adjusting the output threshold, thr, sub-parameter until the sound disappears. The threshold sub-parameter acts like a noise gate by moving the filter cutoff frequency to a lower-than­audible frequency when the input level is below the threshold you set. Because this is not a true noise gate, you may hear a frequency sweep as the frequency moves when the signal level falls to below the threshold you set. Note that gate attack is a global setting (see “Custom settings” on page 30).
Adjusting
All of the filter parameters apply individually to each of the two filters. You can select the parameter to edit, then switch between filter 1 and filter 2, or you can select a filter and then cycle through all the parameters for that filter, or you can do a combination of these—the order in which you edit is flexible.

It is simple on the Wahoo to create reverse (inverted) filter sweeps: simply set freq-hi to be smaller than freq-lo.

FILTER
shape. A musical sound contains many frequencies. A filter is used to remove some of these
frequencies and to enhance other frequencies. The simplest filter to understand is a low-pass filter. It is named after the part of the frequency spectrum that remains after the filtering has happened. A low-pass filter filters out (removes) high frequencies and allows low frequencies to remain (to pass). The frequency above which the high frequencies are removed is called the cutoff frequency, fc.
The Wahoo filters can be configured as low-pass or band-pass filters. A band-pass filter removes frequencies above and below a specified frequency and only allows those frequencies in the specified band to pass. The diagram below shows the frequency response of a low-pass and of a band-pass filter. The centre frequency, rather than the cutoff frequency, is defined for a band-pass filter, both are shown as fc.
i.e.,
2500Hz is shown as “2·50”).

Signal Level [dB]
low-Q mid-Q high-Q
Note that frequencies above the cutoff frequency do not immediately fall to zero. The slope of the curve beyond the cutoff frequency is called the filter roll-off and is a characteristic of the filter. The roll-off is measured in dB per octave and the low-pass filter in the Wahoo has a roll-off of 24dB per octave. The band-pass filter has a roll-off of 12dB per octave on each side of fc. Note that this means the low-pass filter is more effective at removing frequencies above fc than the band-pass filter.
The shape of the filter around the cutoff frequency is another characteristic of the filter and is represented by the parameter Q (or resonance). A high value of Q is associated with a “peaky” filter which has high gain at the cutoff frequency. At maximum Q the Wahoo filters will self-oscillate at fc even with no input signal.
Unlike other filter effects, the Wahoo lets you dynamically change the filter Q as the cutoff frequency changes by using the Q-hi and Q-lo parameters. This gives you enhanced control of the sonic character of the filter and makes it easier to emulate vintage filter effects.
Different effects are achieved using low-pass and band-pass filtering. Low-pass filtering will retain more of the original signal’s low end, whereas band-pass filtering can often introduce more character into the sound.
FILTER
curve. Changing the curve lets you adjust the “feel” of the footpedal, or the response of the
envelope tracker. Take the example of using the footpedal to control the cutoff frequency of the filter. Normally the filter cutoff, from freq-lo to freq-hi, is mapped linearly to the output via the position of the footpedal. The minimum filter cutoff is usually achieved with the footpedal in heel down position and the maximum with the footpedal in toe down position. The filter cutoff is controlled linearly by the position of the footpedal when the footpedal is between its two extreme positions.
The Wahoo allows you to change this mapping from linear to the curves shown below.

Owner’s Manual
This allows you to have more control and configurability of analogue filters than has ever been possible before. If you select one of the lo curves, the filter cutoff changes more rapidly towards the end of the travel of footpedal towards the toe down position. The hi curves change the filter cutoff more rapidly at the start of the travel of the footpedal from the heel down position.
If this seems a little complicated, the best way of remembering how lo and hi work is that a lo curve spends more time near freq-lo, while a hi curve spends more time near freq-hi. The higher the number
i.e.,
Lo9 rather than Lo1, the more pronounced the effect.
For simplicity, we started with the example of how the footpedal controls the filter cutoff. However, in
LFO
, envelope and pitch modes, the same principle holds. Don’t worry too much about how this
parameter works—simply adjust Cur to get the sound you want!
Vocal sounds
To get very vocal-sounding filter effects, you must use both Wahoo filters working together ( operating in the same mode so that they track each other). Doing this lets you approximate the pairs of dominant resonances that are present in the vocal tract when forming vowel sounds. See
“Creating vowel sounds” on page 27 for a table of which cutoff frequencies to set to get various
vowel-like sounds from the Wahoo.

When both filters are in the same mode they can work together to create thick, vocal tones. When the filters are in different modes you can get new interesting effects.

The tempo is in beats per minute, bpm. The sub-parameters bPM, bP.h and bP.L have a range between 10 and 999. To achieve slower and faster tempos, the div sub-parameter multiplies the value of the tempo set by the tyP clock source. As an example, if filter 1 tyP is tPo, bPM is 120bpm and div is 2, and filter 2 tyP is -F1 and div is 1/2, then filter 1 has tempo of 240bpm and filter 2 has tempo equal to 1/2 of 120,
If filter 2 is sync’d to filter 1 (tyP is -F1), then the PhA parameter is used to control the phase offset between the filters. PhA set to 0 means that the filters are in-phase; PhA set to 32 means that the filters are out-of-phase, and settings in-between give degrees of out-of-phaseness. The figure below shows a sinusoid and two examples of different values of the phase offset, PhA.

In envelope tracking mode, the filter cutoff control follows the signal level. The cutoff control increases and decreases as the signal becomes louder and quieter. SEn, the sensitivity sub­parameter, controls how sensitively the filter follows the signal envelope — a high value means that the filter will move easily with gently playing; a low value means that you will have to play hard to get the filter to move much. Att and dEC control how quickly the follower reacts to an increase and decrease in signal loudness, respectively. Pun lets you accentuate the filter response to new notes by providing a boost in sensitivity but only for new note edges, thus making it easier to create punchier, more dynamic sounds. This effect is most obvious with low values of SEn and dEC.
Note that the sensitivity can also be used to tweak the envelope tracker for different musical instruments: for example, a high output bass and a low output bass may need different values of sensitivity to get the same feel. However, we recommend that the global SEn parameter in custom (see “Custom settings” on page 30) is used instead to adjust for instrument characteristics so that it is easier to switch between different instruments and to make it easier to exchange presets with other users.

The pitch mode can be set to either pitch-track or pitch-bend using the tyP sub-parameter. These innovative effects use sonuus’ unique, highly acclaimed, pitch detection and tracking technology.
Top Tip: Pitch tracking is monophonic (it can only track single notes) but you can still
play chords in pitch mode: the Wahoo will track the dominant note. For best control of the effect in pitch mode, play single notes clearly.
Pitch-track (trA). In pitch-track mode, the cutoff frequency of the Wahoo filter is set to follow the
pitch of the notes that you play. There are three parameters that control how this happens. The pitch tracking can be offset from the pitch of the notes you play by adjusting the FrE frequency sub­parameter— a positive number can move the filter frequency higher by up to 4 octaves; a negative number can move the filter frequency lower by up to 4 octaves. The other two parameters that control the pitch tracking are freq-hi and freq-lo in the filter set-up. The pitch tracking frequency is limited to always be between freq-hi and freq-lo. You can picture pitch tracking as a filter that moves with the pitch of your notes within frequency limits you define ( just like when a synthesizer’s filter is set to “keytrack” mode). It allows you to create interesting tonal effects, including synth-like sounds, for example by configuring a low-pass filter to remove the harmonics of your instrument’s signal to leave only the fundamental tone. The tracking will only follow your playing exactly when the curve sub-parameter of the filter ShP parameter is set to linear (Lin). If one of the other setting is selected (Lo9hi9), you will change the point at which the filter follows your playing. Although this will be less predictable, you can create some nice effects like this.
Pitch-bend (bEn). In pitch-bend mode, when you bend a note, the cutoff frequency of the filter
moves. You set how much of a bend should map onto the maximum cutoff control— this is set in semitones via the S.tn sub-parameter and can be between 1 and 36 semitones. Obviously, the larger values are not applicable to note-bending with your fingers; they apply to bending using a whammy/ tremolo bar. The extremes of the pitch-bend are then mapped to the values of freq-lo and freq-hi: the limits you have set for the filter cutoff frequency. The reference point of the bend is set by the rEF sub-parameter. The reference point is the filter cutoff frequency before you apply a bend. For example, if the reference is bottom, then the filter cutoff is at freq-lo before you bend. Bending up by S.tn causes the filter cutoff to increase to freq-hi. The effect of different reference points is shown in the diagram below.

Creating vowel sounds
To create convincing vowel sounds, you need to use both Wahoo filters working together to produce the characteristic frequency components of the desired vowels. The table below shows typical cutoff frequencies that can be set on each filter to obtain each vowel sound. Note that these values are approximate and are a good starting point. From here you can adjust the frequency and Q of each filter and experiment to see what sounds most vowel-like to you. Also try configuring one filter as band-pass and the other filter as low-pass to get variations of the sound.
How to use: to go from “ee” to “ah”, set freq-lo to the “ee” values, and freq-hi to the “ah” values.
Vowel
ee 300 2700 i 400 2500

User modifications of the Wahoo
For the avoidance of doubt, opening any part of the Wahoo other than the battery compartment will always cause your warranty to be invalid.
However, we realise that musicians sometimes make the minor modification of reducing the footpedal travel by sticking a piece of rubber under the front (heel position) of the footpedal. If you do this, you will need to follow the pedal calibration procedure below (page 33). Any damage caused to the Wahoo deemed by sonuus to be caused directly or indirectly by this (or any other) modification will not be covered by the warranty.
The rubber stop at the back of the footpedal (under the toe position) should never be modified to avoid damage to the pedal sensor.
Filter calibration
The Wahoo uses analogue filters and a pure analogue signal chain. These analogue electronics can be sensitive to temperature changes. To ensure presets continue to sound the same each time you use them, and so you can exchange presets with other Wahoo users and get the same sound, the Wahoo uses temperature-compensated calibration. Calibration has been done in the factory before you receive your Wahoo, but you may want or need to adjust this, for example if you are using the Wahoo in a particularly hot or cold environment.
Calibration has the best results if the Wahoo has been on for at least ten minutes so it can warm up to a stable temperature. If you calibrate the Wahoo in a warm room straight after you have brought it in from a cold car, the calibration may not remain accurate as the Wahoo warms up.
For calibration, the Wahoo outputs a tone by making the filters self-oscillate. To see this tone you need to connect the output of the Wahoo to a tuner that can tune 880 Hz (A5). Enter calibration mode by simultaneously pressing and holding the is displayed. Now adjust the
