Connections
Input Side Connections
Input 1
This is the primary input for guitar, bass, or other instruments. It can also accept line-level inputs.
Connect it to your instrument or other audio source using a mono (TS) ¼” cable.
Input 2
Input 2 can act either as an audio input or as the data connection for the Neuro App, or both at the
same time.
Input 2 as an Audio Input
The tip contact on Input 2 acts as a secondary input for guitar, bass, or other instruments. It is only
active when the Kingmaker is configured with a signal routing that uses stereo inputs. Connect it to
your instrument (or the previous effect in the signal chain) using a mono (TS) ¼” cable. By default,
the Kingmaker will auto-detect the routing mode. Other routing options are available using the
Neuro App. For more information about stereo routing, refer to the Stereo Routing section.
Input 2 as a Neuro App Data Input
The ring contact on Input 2 acts as a data connection for the Neuro App. Connect it to your mobile
device using a stereo (TRS) ¼” cable. It can also accept daisy-chained Neuro data from another
Neuro-compatible pedal in the chain, provided that a TRS cable is used. The audio signal (if
applicable) will be on the tip contact of the plug, and the Neuro App data will be on the ring contact.
Input 2 only accepts data from the Neuro App. Data from the Neuro Hub comes from the Control
Input port.

Power and Control Connections
DC 9V (Power)
Connect to the included 9 Volt DC power supply. The power supply must be regulated at 9 Volts
(direct current), able to source at least 180 mA (milliamps) of current, and the plug should have a tipnegative, sleeve-positive polarity (the center tip is ground and the sleeve is power).
USB
Connect to your computer (Mac or Windows) to the Kingmaker’s USB port (denoted by the
icon) using a standard mini USB cable. The Kingmaker is a class compliant USB device, meaning that it
should be recognized by Mac and Windows computers automatically. For more information about
the Kingmaker’s USB capabilities, refer to the USB section of the User’s Guide.
Control Input
The 3.5 mm Control Input port connects to external control devices such as the Dual Expression
Pedal, Reflex Universal Expression Pedal, Neuro Hub, and Hot Hand Motion Controller. For more
information, refer to the Expression Pedal Input, Hot Hand Input, and Neuro Hub sections of the
User’s Guide.
SA245 Kingmaker Fuzz User’s Guide 7
Clean signal: With no distortion, the guitar
signal passes through the circuit unaffected. In
this example, a pure sine tone is used as a test
signal.
Tube/transistor saturation (soft clipping):
Tube and transistor amplifiers enter a
saturation state when overdriven and start to
distort the shape of the signal. This involves
some soft clipping at the peaks and valleys of
the signal, and may be symmetrical or
asymmetrical in shape.
Asymmetrical:
Symmetrical:
Diode clipping (hard clipping): Diodes can
clamp or limit the signal to a maximum level.
Symmetrical hard clipping: The signal clips
equally on the top and bottom.
Asymmetrical hard clipping: The signal clips at
different levels on the top and bottom. This is
characteristic of the Fuzz Face and is included in
the Kingmaker’s Normal circuit.
Overshoot: Depending on the characteristics
of diodes and transistors in the circuit, the
signal may exceed its normal clipping point
before settling, which is known as overshoot.
Basic Fuzz Operation
Fuzz is a type of effect that works by distorting the input signal. Distortion can occur in a variety of
ways and results in a wide variety of outputs. This table shows a simple representation of what some
different types of distortion look like.
SA245 Kingmaker Fuzz User’s Guide 8
Extreme overshoot: The overshoot
phenomenon can be taken to its extreme for
fuzz and metal sounds. This is characteristic of
the Big Muff Pi and is included in the
Kingmaker’s Heavy effect circuit.
Octave: A rectifier can be used to double the
frequency of the signal, creating an octave fuzz
effect with a unique tonal character. This is
characteristic of the Octavia, and is included in
the Kingmaker’s Octave effect circuit.
The various drive circuits in the Kingmaker Fuzz utilize a combination of these different approaches
to create tones inspired by the classics, as well as new groundbreaking tones that bring their own
unique flavors.
Effect Types
The Kingmaker includes three basic fuzz types, with more effects available in the Neuro mobile app.
Heavy
The Heavy circuit offers the extreme in guitar fuzz. Plenty of low-end and endless sustain creates a
“violin” like fuzz.
Normal
The Normal circuit generates a vintage fuzz that is a bit cleaner than the Heavy circuit. This highly
transparent fuzz delivers that damaged speaker sound that has graced so many great records.
Octave
The Octave circuit generates a soaring octave up effect along with some very nasty fuzz. Try turning
down the tone knob on your guitar to really bring out the higher octave.
Additional Effect Types
Additional effect types can be loaded into the Kingmaker using the Neuro App on your mobile device
(iOS / Android) or the built-in USB port (Mac / Windows).
The Kingmaker Fuzz is compatible with Source Audio’s Overdrive and Distortion effects, so it is
possible to load Overdrive, Distortion, and Fuzz effects on the Kingmaker at the same time.

Knobs
Drive Knob
The DRIVE KNOB adjusts the amount of gain applied to the signal. Dial down the drive for a cleaner,
more articulate tone or crank it up for over-the-top doses of fuzz.
Level Knob
Adjusts the output level of the effect. This is useful for setting the level of the fuzz effect compared
to the bypassed signal. Note that because the fuzz effect compresses the signal in the
clipping/saturation stage, the dynamic range of the distorted signal will be less than the dry signal,
and the LEVEL KNOB can be used to compensate for the loss of level that results from this compression.
Bass Knob
The BASS KNOB adjusts a low shelf tone control. Turning the knob clockwise will boost the bass;
turning the knob counter-clockwise will cut the bass.
Treble Knob
The TREBLE KNOB adjusts a high shelf tone control. Turning the knob clockwise will boost the treble;
turning the knob counter-clockwise will cut the treble.
SA245 Kingmaker Fuzz User’s Guide 10
Effect Switch
Selects between the three basic Fuzz effect types – Heavy, Normal, or Octave. These effects are
described in further detail in the Effect Types section.
LEDs
Engage / Bypass LED
The ENGAGE / BYPASS LED above the footswitch indicates if the Fuzz effect is active (lit green) or
bypassed (not lit).
When the user preset mode is enabled, the LED will turn red. See the Preset Storage and Recall
section for more information about user presets.
External Control LED
The small LED located between the Depth and Speed knobs is the EXTERNAL CONTROL LED. When lit, it
indicates that external control mode (expression, hot hand, or MIDI) is active. For more information,
see the External Control section.
Footswitch
Enables or bypasses the Fuzz effect.
Control Input Button
This small button is used when configuring external control. See the External Control section for
more details.
Preset Storage and Recall
The Kingmaker features a user preset that can be easily saved and recalled using the footswitch.
When a preset is recalled, all of the parameters instantly jump to their saved value, regardless of the
position of the knobs. This allows you to save your favorite sound without having to worry about the
knob positions.
Saving Your First Preset
Bypass the Kingmaker by clicking the ON/OFF FOOTSWITCH once. The ENGAGE/BYPASS LED should
be dark at this time.
Press and hold the ON/OFF FOOTSWITCH for 5 seconds and wait for the ENGAGE/BYPASS LED to turn
red. You are now in preset mode.
Set up the effect how you want it to sound, including the EFFECT SWITCH, LEVEL KNOB, DRIVE KNOB,
BASS KNOB, and TREBLE KNOB. Once you have made a change, the ENGAGE/BYPASS LED will begin to
blink.
To save your preset, hold the footswitch until the ENGAGE/BYPASS LED blinks rapidly 3 times.
Now you can engage and bypass the Kingmaker using the ON/OFF FOOTSWITCH, and each time
you engage the effect, your saved preset will be recalled.
Editing a Preset
Activate your preset (the ENGAGE/BYPASS LED will be solid red).
SA245 Kingmaker Fuzz User’s Guide 11
Change any parameter you wish (EFFECT SWITCH, LEVEL KNOB, DRIVE KNOB, BASS KNOB, and TREBLE
KNOB). Once you have made a change, the ENGAGE/BYPASS LED will begin to blink.
When you are ready to save, press and hold the ON/OFF FOOTSWITCH for a few seconds. The
ENGAGE/BYPASS LED will blink three times to show that the preset was saved.
Exiting Preset Mode
When Preset Mode is active, bypass the effect using the ON/OFF FOOTSWITCH. The ENGAGE/BYPASS
LED should be dark at this time.
Press and hold the ON/OFF FOOTSWITCH for 5 seconds and wait for the ENGAGE/BYPASS LED to turn
green. You have now exited Preset Mode.
Universal Bypass TM
Most effect pedals offer either true bypass or buffered bypass. The Kingmaker contains two separate
circuits for bypass mode, allowing you to choose the method you prefer. The true bypass path uses
signal relays, which are electromechanical switches. This provides an ultra-low resistance path from
the input jacks to the output jacks, which is effectively the same as a wire. The buffered bypass path
uses extremely low noise buffers, which provide a very low output impedance and are effective for
driving long cables or long chains of effects following the Kingmaker’s audio output.
Out of the box, the Kingmaker operates in true bypass mode. In order to switch to buffered bypass
mode, edit the Kingmaker’s global settings using the Neuro App.
We recommend you choose between the active analog bypass (a.k.a. buffered bypass) and relaybased true bypass based on what is needed in your signal chain. Ideally, the first pedal in a signal
chain is a buffered input followed by true bypass in the rest of the signal chain.
Both bypass methods have pros and cons associated with them. Buffered bypass provides consistent
input impedance so that if the source is susceptible to variations in input impedance (similar to a
guitar pickup), there won’t be a noticeable change in tone. True bypass has the benefit of providing a
dedicated hardwired bypass signal path. The Kingmaker features small-signal relays for true bypass
switching that offer reduced pops and clicks compared to the traditional true bypass switching
method using a mechanical switch.
Stacking and Parallel Processing “Inside the Box”
The Kingmaker works great as a simple mono Fuzz effect, but it has the power to do much more.
Within the Kingmaker, two completely independent overdrive, fuzz, or distortion circuits can be set
up to run stacked (in series), in parallel (side-by-side and mixed), or even in true stereo. Usually, this
would require two separate distortion pedals, but the Kingmaker can do it all on its own.
Stacking (Series / Cascaded)
Stacking overdrive, fuzz, and distortion pedals is a common method for creating unique textures that
would not be possible with a single pedal. This normally involves putting two pedals in series, one
after the other, to create multiple gain stages. Typically, this requires two separate distortion pedals,
but the Kingmaker can do it all internally. Each of the two drive stages, called A and B, can be
configured independently using any overdrive, fuzz, or distortion circuit, with its own independent
