gig-fx PRO-CHOP

There's really a lot packed in this pedal but it's not hard to orient yourself, especially if you already are familiar with tremolos and phasers. The functions are what you'd expect and it has knobs to twist and a foot pedal to depress rather than a tiny menu screen or something silly like that...

It's a liquid sounding, pulsing, panning sort of trip so buckle up. You can get near synth-sounding stuff and play along with the time you set for the pan/trem for cool sounding notes that'll telegraph from amp to amp (two amps is the way to go for this pup).

no issues. It gets weird when the battery is low.

Very satisfied here. Timely and friendly service. Extra helpful.

Good product with original concept and features. Sets itself apart from other standard trems. Instant gratification factor 10. Can be morphed to fit into or inspire song ideas. Transforms an ordinary playing experience into something useful and trance-like. Get one.

Square-wave tremolo (chopper)+classic tremolo, both working independently, possibly together (!) while used in stereo. Speed/frequency fo both tremolos (tremoli?) is controlled whether by expression pedal or classic knob (then the pedal sets effect on/off). The pulse width of the chopper's square wave can be set using a "ratio" knob, enabling from large chopping to machine-gun-like tac-tacs. So is the depth/intensity of the classic tremolo using a "depth" knob, enabling from slight to silent-phase tremolo.
MIDI in for tempo synchro using MIDI-clock signal (did not test it yet). All analog circuitry digitally controlled. One input, two outputs for stereo (works in mono).
Very easy to use, whether in classic on/off mode or bizarre mode with the speed controlled by foot. Great fun finding desired speed using the pedal, weird but inspiring.

This pedal works great in stereo. The chopping sound is bouncing from left to right, it sounds great! The classic tremolo, used in stereo, becomes a panner that travels the signal gradually from left to right, like someone playing with the pan knob of the mixer. There you can use the two effects together. Hear the samples on Gig-Fx's website, it's eloquent.
The chopper sounds very...organic (what an adjective, eh?), especially when fine-taylored setting the appropriate pulse width. While chopping sharp, it does not have this "harsh-attack" that other square-tremolos have. I don't know if it is the analog circuitry, but it's great.
When the effect is on and the signal silent, at high volume, you can hear a slight regular "at tempo" little "pop". Must be the pulse of the chopper's square wave. No problem. And if the signal is silent, why not turn it off and go bypass? And then it is magic. It is very uncommon to say that one of the best features is when there is no effect, but it is. GREAT BYPASS! Transparent, as if the pedal was not there. I use a Gibson Fying V with ceramic high-level pickups, and there is absolutely no signal loss, only the mono guitar signal goes stereo. I did not know I bought myself an excellent stereo splitter. Great for dual-amping!

Strongly built. The pedal's resistance can of course be adjusted.

I contacted the company by email for technical questions before buying. Prompt, kind and accurate answers from the boss himself and forwarding feedback from design engineer. They also quickly responded to my (yes, highly written) feedback.

In my opinion this is the most complete product in this category. And sounds incredible. I confess that I am a little bit enthusiastic, but anyway...Wow!
While looking for tech-like beat-synchro tremolo-filter guitar effects, I first bought myself Roger Linn's Adrenalinn III. Although greatly mind-designed (in theory), the little box did not pass the practical exam. At high volume through an overdriven channel, you can hear digital computer-calculating noises, and in bypass there is a significant signal loss. I intend to buy later Gig-Fx's Mega-Wah, couple it to the Pro-Chop and build myself a killer modulation-effect set.
