This pedal is the new mini version of the Air Traffic Controller – but with a switchable filter. The overdrive circuit (not switchable) is from the – now discontinued – El Distorto, so this is actually a two-in-one pedal. With the filter on and some white noise blended in it gives a’ moogy-soloing’ hi-resonance funk sound, or a stinging and intense lead tone. Filter off gives our tweaked mid-rangey optimum fuzz (as loved by Billy Gibbons).

White noise hiss is a feature often ignored in ‘synth’ pedals, but it can add a great texture to the tone. Here it’s blendable; have none at all, just a clear zing – or crank it up towards electro percussion….

There’s also volume and drive controls, a ‘hi/lo’ resonance button, and an ‘incoming’ signal indicator. It’s powered by standard 9v PSU (centre earth) – not included.

This is actually the most flexible pedal from Rainger FX, covering guitar sounds that range from chunky and straightforward, or with a more electro edge, through to noise-based percussion guitar.
