Discovery Delay – OverviewOverview
Overview
e long-standing mission of Suhr has been to bring the simplicity and tone of analog circuitry to today’s guitarists� e Suhr Discovery Analog Delay is the new revolutionary pedal, designed by Kevin Suhr� e Discovery Analog Delay is the rst of
its kind, for Suhr and the world�
Retaining the tone, vibe, and creative inspiration of iconic analog delay units, yet
adding the versatility of the most modern and expandable delay pedals available
today�
e nest analog delay packed with 127 savable preset spaces, Tap Tempo, High/Locut, with every parameter mappable to an expression pedal per preset, MIDI ins and
outs, and every parameter you could ask for� at’s just the beginning�
e Suhr Discovery Analog Delay is a product that has been years in the making�
We took our time with this one to make it as perfect as we could in the smallest
package, full of features that include a few no other analog delay has�
We knew we wanted an amazing bucket brigade style analog delay� We also knew
that having only one setting was not enough for the endless amounts of sounds that
could be achieved� at is why we allowed you to save up to 127 presets, recallable
via MIDI� All knobs are programmable for each preset, and can also be controlled
individually via MIDI� We didn’t stop there� We allowed you to program the expression pedal dierently for every preset to control every knob in any direction desired�
We didn’t stop there� We allowed you to dump all your presets to a MIDI Sysex le
for backup on a computer� You can even transfer presets between units�

Discovery Delay – TerminologyTerminology
Terminology
Here is a list of a few common terms used in this manual� Please familiarize yourself
with the terms you do not already know� Understanding these terms will better help
you understand how to use the Discovery Delay, or any delay for that matter�
Signal
A signal in this text refers to an audio signal, which is a representation of sound in
the form of changing level of electrical voltage� Such a signal can come from your
guitar pickups, through your guitar cable and into the Discovery� It may also come
from previous eect, or from your ampliers eects send�
Dry signal
e Dry signal refers to your unaected guitar signal, or whatever signal that has
been connected to the input of the Discovery� is has no delay eect on it� When
the pedal is bypassed, all you are hearing is the dry signal�
Wet Signal
e Wet signal refers to the delay eect itself only without any dry signal� A delay
makes a copy of your dry signal, and plays it a certain amount of time later, which
creates the wet signal� e Dry and Wet signals are then mixed to form the nal output signal�
Repeats
Repeats is a term used among users of Delay eects that refers to the actual repeated
dry signal that make up the wet signal� e wet signal is a repeated copy of the dry
signal that feedbacks into itself and keeps repeating what you play into it� Repeats
are also commonly referred to as “echoes”
Milliseconds (ms)
A millisecond is 1/1000 of a second� Milliseconds are abbreviated as “ms”� us, it
takes 1000 ms to make up 1 whole second�

Discovery Delay – TerminologyTerminology
Beats Per Minute (BPM)
‘Beats Per Minute’ refers to the tempo (speed) of a piece of music� A beat refers to a
quarter note in a measure, so 4 beats would equal 1 measure� 120 BPM would equate
to 120 quarter notes in a minute if only quarter notes were played for a whole minute�
Modulation
To modulate is to continually change the value of a parameter� In the case of this
delay, the parameter that is being continually altered is the delay time� e delay
time is “wiggled” a certain amount of time before and aer the center time, causing
a change in pitch in the wet signal� e amount of wiggle is determined by the Speed
and Depth controls� When this changing pitch on the wet signal is mixed with the
dry signal, the result is a chorus type eect, which sounds like multiple voices are being played at once�
MIDI
MIDI is an abbreviation for Musical Instrument Digital Interface� is is a standard
of digital communication between musical instrument devices that was developed in
the 1980’s in collaboration with a few music manufacturers� Today, it is the leading
communication protocol between musical instruments� MIDI allows you to change
presets and control knob positions on the Discovery from any device that can send
MIDI information�

Discovery Delay – Inputs & OutputsInputs & Outputs
1. 18VDC Power Input
e Discovery Analog Delay requires an 18V, center negative power supply with
250mA of available current. For more details, refer to the technical specications on
page 37.
2. External Switch (Stereo TRS 1/8”)
e External Switch allows you to plug in a TRS 1/8” (3.5mm) cable to connect a
momentary dual foot switch to control the pedal in one of 3 modes.
It can be used to change presets, jump across presets, externally control the bypass
and tap switches, and send MIDI program changes.
For more details about the dierent modes for the external switch and how to set it
up, refer to page 32.
3. TAP External Switch (Mono TS 1/4”)
e TAP jack takes a momentary foot switch to externally control the delay time tap
tempo.

4. Output (Mono TS 1/4”)
Plug the output of the eect to the next device.
5. Expression Pedal (Stereo TRS 1/4”)
e expression pedal input allows you to connect a low impedance 10K ohm expression pedal to control all the knobs per preset� For details on how to use the mapping
process for the expression pedal, refer to page 20�
6. Input (Mono TS 1/4”)
e input should be connected to your guitar, the previous eects output, or the effects send of an amplier or mixer�
7. MIDI In (5 PIN DIN)
e MIDI IN uses the standard DIN 5 connection for MIDI communication� Uses
for this are changing presets, syncing delay time to MIDI clock, and controlling all
parameters� Refer to the MIDI section in this manual for more information
8. MIDI Out/Thru (5 PIN DIN)
e MIDI OUT/THRU jack is used to pass MIDI communication from the MIDI IN
jack to the next device� Depending on the global settings, this output can be set as a
hardware through for ultra low latency when no MIDI information is to be generated from the Discovery itself� When set as an output, the Discovery delay can send its
own messages such as Program changes and Controller changes� is can be used to
control other pedals� For more information, refer to the MIDI section on page 23�

Controls
Bypass Foot Switch
e bypass switch has a few functions
1� To bypass (turn o) the eect
2. To jump to a lower adjacent preset when in “Preset Mode”
3. To select a preset when using an external 2 button foot switch in the EXT SW jack
e Discovery delay has the option to bypass the eect in two ways���
True Bypass (input is physically connected to output, completely taking all circuitry
out of the signal path� is will cut o any echoing repeats)�
Buer Bypass (the input to the delay path is disconnected, leaving the delays to
“Trail” until they decay and leaving the guitar without the eect)�
Refer to the global settings section to select whether the bypass is in True or Buer
bypass modes�
Tap Foot Switch
e tap tempo switch will count the amount of time between switch presses and set
the delay time to that time when division is set to Quarter Note�
How it Works:
e Discovery utilizes an averaging algorithm that will average the last 4 successive
taps, and drop the oldest tap aer 4� If not pressed for longer than 1�5 seconds, the
tap averaging restarts�
Going into “Preset Mode”:
Holding down the Tap switch for 1�1 seconds will put the pedal into “Preset Mode”,
in which the Bypass and Tap switches take on new functions of decrementing and
incrementing which preset you are on� is allows you to easily change presets with
your feet�

Mix Knob
e [MIX] knob mixes in (or out) the delay eect� It also mixes in or out your guitar
signal�
100% Dry / 0% Wet
100% Dry / 100% Wet
0% Dry / 100% Wet
From full counter clockwise to the middle, the knob is mixing the wet delay eect
from 0-100%
From middle to full clockwise, the wet delay eect stays 100%, while your dry guitar
signal fades out from 100% to 0% (at full clockwise)�
When the mix knob is 50% on (half way), it is 100% dry + 100% wet
Time Knob
e [TIME] knob can be used to:
1. Alter the milliseconds (40-1100ms in 5ms increments)
2. Alter the BPM (range from 55-250BPM)
depending on which is shown on the display�
e arrow buttons can also be used to push the delay beyond these limits, or increment by singular millisecond or BPM values�

Discovery Delay – ControlsControls
Regen Knob
e [REGEN] knob sets the amount of feedback o the delay back to its internal
input mixer� is controls how long the delay repeats last until they decay away�
Due to the internal limiter in the regen circuit, maxed out regen settings allow for
distorted self oscillations and sound eects�
Hi Cut Knob
e high cut reduces high frequencies from the delayed signal, giving you a “darker”
sound commonly associated with bucket brigade analog delay pedals�
Fully counter-clockwise is the brightest and clearest tone� For the classic warm vintage style analog delay tones, set the knob past half way� e high cut knob also helps
reduce noise and should be experimented with when running into the front of an
amp or gain stage for desired tone/noise�
For the clearest low noise delay eect, place the Discovery in the eects loop of your
amplier and keep the hi cut knob fully counter clockwise�
Lo Cut Knob
e [LO CUT] reduces bass from the delayed signal only� is is helpful to echo the
frequency ranges that you want to and prevent extra bass from muddying up your

maximum low cut�
Speed Knob
e [SPEED] knob controls the speed of a LFO (low frequency oscillator), which
controls the delay time around the center of what is displayed on the display� Changing the delay time automatically like this causes an audible pitch bend in the delayed
signal, causing a chorusing eect� is is commonly known as “modulated delay”�
Depth Knob
e [DEPTH] knob controls how intense the modulation of the delay is� With full
clockwise positions, you will notice audible pitch bending on the delayed signal� At
full counter-clockwise positions, there is no modulation�
