Welcome to the Creative World of the GTC Sound Innovations REVPAD
Welcome to the Creative World of the GTC Sound Innovations REVPAD
The GTC Sound Innovations REVPAD is a sound effect controller for use with amplied instruments. It includes a sound processing
base unit, which can connect to other equipment or systems. It has a Touchpad, which attaches to the guitar and communicates wire-
lessly with the base unit. The Touchpad attaches to the guitar by an adhesive that does not damage or otherwise affect the surface of
the instrument. The base unit contains algorithms that provide a great number of effects, in addition to analog distortion and overdrive,
and includes the possibility to change effects while playing.
The REVPAD includes multiple Patches (presets) of effect parameters, including analog distortion and overdrive, as well as additional
effects, such as chorus, delays, and virtual faders. It enables the user to manipulate sound effects by swiping or tapping the Touchpad
surface and allows for improvisation and creating new effects on the y. The REVPAD enables smooth cross-fading between effects,
a dynamic kill switch, a virtual whammy bar, volume control, ambient sounds, and control of external gear, such as a favorite pedal.
With the REVPAD the user can manipulate the wah and virtual whammy bar, change volume, apply cross-fading, and create varying
levels of feedback more easily than by using the knobs on the guitar.
The REVPAD supports your creativity to explore the limitless world of sound effects.

Quick Start
Quick Start
The REVPAD Touchpad provides a wireless connection to the REVPAD Base Unit so you can switch and control effects with a swipe
or tap of your nger.
Driven by the TouchFx Patented Technology engine, the REVPAD provides guitarists full, simultaneous control of multiple effects pa-
rameters, including their own existing pedal board effects. This enables the player, for the rst time, to actually play effects on the y,
instead of in a standard manner, and combine this naturally with playing the guitar.
Up to eight effects and their parameters can be simultaneously assigned to any axis on the pad and by that to actually perform as
“virtual” faders and switches for any aspect of the signal and its processing. It gives the player full, accurate and super-dynamic control
of the effects with just a simple nger tap, touch or swipe. It also eliminates the need to go to the pedal board to change effects and
the hassle of bending down and tweaking knobs while playing.
Three buttons located on the REVPAD Touchpad can be assigned to operate many great features offered by the REVPAD. They can be
used to switch between Patches, go through different modes, bypass, freeze, MIDI applications and much more.
Before exploring how to customize the REVPAD to t your personal way of playing, let’s see what it can do by itself.

The REVPAD Base Unit
It’s all about preserving the natural sounds and soul of the guitar. The REVPAD is not generating sounds but processing them, so even
though you can get synth-like sounds it is not a synthesizer, rather a signal-processing unit that preserves the natural sound of the
instrument as well as the natural response to and feel of the guitar player’s ngers.
The REVPAD System offers 200 factory and user presets to build and explore your own sounds.
Building a Patch is easy and intuitive:
■Step 1: Choose any effect you want.
■Step 2: Explore the effect to set parameters.
■Step 3: Push a button to select which one of those parameters you’d like to be controlled by the Touchpad and in which direction:
X+, X-, Y+, Y-.
Repeat those three action steps to all of the other effects you’d like to add to the effect chain and press the save button. That’s all you
need to do to build a fully customized Patch.
