An innovative pedal that will challenge your imagination and creativity.
The Gig-FX Pro-Chop Tremolo Guitar Effect Pedal opens up a whole new world to guitarists and other musicians who want to produce repeatable and trancelike grooves or pulsating effects that are in perfect sync with any track.
There are two ways to achieve this; one is by setting the frequency read out on the LCD to the chosen tempo. This allows for the first time ever a precise and repeatable tempo for a tremolo wave / chop / pan.
The second is by syncing with any track / synth that has a MIDI clock available. By syncing with a given MIDI clock beat, the Pro-Chop effect pedal can allocate 1.2.3.4 or 8 chops / pans / tremolo waves allowing a wide variety of sound patterns. Whenever the device is turned on, it will be instantly in perfect sync.
The output signal from the Pro-Chop tremolo pedal may be mono or stereo, but is infinitely more interesting in stereo. In stereo, the effect can be panned or "chopped" from one channel to another and combined in phase or out of phase in various ways to produce an infinite number of captivating sounds. Merely describing it will not do it justice. You have to hear it to believe it!
There are two waves (oscillators) on the Gig-FX guitar pedal, one is a square wave which produces the chop sound and the other is a triangle wave which provides the tremolo or pan. Both waves run independently. On the left side of the unit, the controls adjust the chop attributes, and on the right side, the controls adjust the pan and tremolo attributes. There is a Mode Selector Switch which allows you to choose Chop only (CHOP), Tremolo / Pan only (STIR), and either of two combinations of both (BLEND and SHAKE).
In mono, when you turn the Chop on, the sound will be turned on and off at the rate and ratio you choose. In stereo, when one side is off, the other side is on, so the signal bounces back and forth across the sound stage. Try it on a big stage and the audience will be knocked out.
In pan / tremolo mode, in mono, the device will provide a versatile tremolo effect that allows the signal to be modulated deeper and slower than all other tremolo units, and the tempo can be set on the fly. In stereo, one side is on while the other is off, so the sound pans gradually from the left to the right at a rate determined by the rate control or pedal.
When you select the Blend or Shake modes, in mono, you hear the two waves beating against each other. In stereo, the Gig-FX Pro-Chop gives you rhythmic pulses flying across the room.
