1. Controls
(9) (10)
(1) STYLE knob selects from the range of Talkbox and Synth sounds.
See Chapter 2: Using the Style Knob for details.
(2) CORRECTION knob adjusts the amount of pitch correction. With the knob
at the center 12:00 position, the effect will provide subtle pitch support
without noticeable or unnatural artifacts. Turn the knob all the way up for
a more aggressive effect, or fully counterclockwise to turn the effect off.
Correction is inactive while Talkbox or Synth effects are engaged.
(3) REVERB knob selects the type and amount of reverb effect on your voice.
The 3 types of reverb appear in order from the smallest space (Room) to the
largest (Hall). Adjusting the knob within your preferred reverb
space determines how pronounced the effect will be.
Turning the knob fully counterclockwise turns the reverb off.
Reverb is active regardless of the on/off status of the Talkbox Synth effect.
(4) BATTERY LED indicates the battery level, with green showing full life,
yellow being partial life, and red to alert that the batteries
should be changed.
(5) TONE button engages a preset combination of adaptive EQ, compression,
de-essing, and noise gate. “Normal” and “Less Bright” settings can be
toggled by holding the Tone button and pressing the footswitch.
(6) ON/OFF LED lights when the effect is engaged.
(7) FOOTSWITCH bypasses the Talkbox or Synth effect,
but does not affect the reverb or Tone status.
(8) USB input accepts a micro USB cable for connection to a computer. Use the
VoiceSupport application to install firmware updates, and for other features
depending on your product.

(9) ON/OFF switch powers the pedal on and off. To prevent audible thumps,
ensure PA level is down before powering off unit.
(10) POWER input accepts a 9V power cable (not included).
(11) OUT jack accepts a balanced XLR cable for connection to a
mixer or active speaker at approximately mic output level.
(12) MIC input jack accepts a balanced XLR cable to connect your microphone.
(13) GUITAR IN jack accepts a 1/4" TS cable to connect your guitar.
(14) GUITAR THRU jack sends your guitar signal out via 1/4" TS cable.
2. Operation
Micro USB cable
MP-75 microphone
Mixing board
Power cable
• Connect a microphone to the MIC jack
Momentary Mode
• Connect the OUT jack to a mixer, interface or active speaker
The standard function of the footswitch is a latching style, meaning that each
press of the footswitch turns the effect on and off. Alternatively, the pedal can
operate in momentary mode, meaning that the effect is only active while the
footswitch is held down. As soon as you release the footswitch,
the effect is bypassed.
• Connect a guitar to the Guitar Input jack on the right side of the pedal
• Connect the left Guitar Output jack to an amplifier or mixing console
• Connect a micro USB cable to a computer
• Connect power cable
Using the Pedal
To switch the unit to momentary mode, hold the Tone button down while
powering the unit on. Repeat the process to return to latching mode.
Changing the Batteries
Vocalize into the mic while playing guitar to hear the effect. Don’t worry about
singing in tune; the pitch of the effect comes from your guitar.
Talkbox Synth can operate on 4 AA batteries. Remove the single screw on the
bottom of the pedal to open the battery door. Make sure to observe correct
polarity when inserting the batteries.
Over-enunciate your vowels to get more interesting and expressive effects.
Auto Gain
You can play guitar chords with Styles 1-4 but only monophonically (one note at
a time) using Styles 5-8. A light picking touch helps with tracking.
Talkbox Synth will automatically adjust the gain setting for your microphone,
eliminating the need for manual adjustments and ensuring that a good signal is
passed to the mixer without any unwanted distortion.
Classic, Modern and all Synth styles mute the guitar output to INST THRU. The
guitar is unmuted only on the Classic+ and Modern+ styles.
Using the Style Knob
Turn the knob to select which effect you want. There are two sets of styles:
Talkbox (1-4) and Synth (5-8). See the table below for descriptions.
1. Classic – This most closely imitates the sound of a saturated (distorted) horn
driver piping your guitar sound into your mouth.
2. Modern – This style is clean and clear to mimic a vocoder effect.
3. Classic + – This produces the same sound as Classic but unmutes the dry
guitar sound from the Guitar output for a duo effect.
4. Modern+ – This produces the same sound as Modern but also unmutes the
guitar sound.
5. Synth 1 – Two synthesizer voices triggered by your guitar are slightly
detuned for a chorused mono synth sound.
6. Synth 2 – A single fat, square wave synth voice produces a rich sound almost
like a totally saturated distorted guitar tone.
7. Synth 3 – A pair of detuned, octave down synth voices make a bassy,
chorused effect.
8. Synth 4 – A unison voice with a fifth above make a classic synthy sound.
Adjusting Style levels
You are able to raise or lower individual style levels to suit different guitars and
sound requirements. Load the style you want to adjust then hold the Tone button
while turning the Correction knob. The middle detent on the Correction knob
represents the factory level adjustment; to the left (counterclockwise) is quieter
and to the right (clockwise) is louder. Releasing the Tone button stores your new
level until the next time you require a change.
After setting, re-adjust the Correction knob to where you want it when singing
without the Talkbox or Synth effects.
Guitar Connection Tip:
Guitar – Placing Talkbox Synth as the first device in your pedal chain will give it
the cleanest signal with which to drive the synth sounds. If you prefer to have
other pedals before, optimum synth tracking is derived when their effects are off.
24 V Phantom Power
Phantom power is always active on the Talkbox Synth. This will power
condenser microphones, but will not affect dynamic mics either.
Mic Control
Mic Control allows you to control the effect's on/off status via an
MP-75 microphone. Press and hold the footswitch while powering up the unit
to toggle Mic Control.
Note that when using a condenser microphone, Mic Control should be disabled to
prevent unwanted on/off switching.
