Incredible Fuzzz pedal!

This is an extraordinary fuzz pedal, it’s quite unique.

It’s hard to describe exactly, like many David Rainger creations.

There have been many versions of the Dr Freakenstein fuzz. This is the latest version as of 2026. The fuzz - which I can only describe as the heaviest Tonebender-like gated fuzz I’ve ever heard - can’t be turned down, or blended with a dry level. It’s fixed, apart from its volume, which can go incredibly loud. Its tonality can be controlled, using an overtone knob. The overtone knob is like a low-pass resonant filter on a synth, with a definite resonant peak (it’s not just a low-pass, there’s a definite resonance spike). To the left is a bank of knobs and switches controlling the LFO. The LFO can be switched on or off, and it introduces a sweeping phase-shifting effect. There’s a toggle for this which can be used to set the rate of this phase shift cycle, and two knobs above it control the speed. ‘Slow’ moves the phase from a gentle sweep to a fairly fast wobble. The ‘fast’ knob takes the modulation into the audio range; in other words, it adds an additional note to your tone, much like a ring modulator. The LFO can be manipulated at the same time as the overtone knob, to produce some truly stunning fuzzed-out synth effects.

Finally, in the middle, there’s a simple ‘chop’ switch, which introduces a 100% wet square wave tremolo effect (think ‘Spacemen 3’), with a wide-ranging rate control.

The pedal comes supplied in a dayglo 1970s ‘Clockwork Orange’ glam-rock box! Indeed, the whole pedal is sort of reminiscent of some of the more ‘out there’ phase-shifted fuzz effects you heard on the more adventurous glam rock and punk records in the 1970s. It’s fabulous! The pedal also comes with Rainger’s pressure-sensitive ‘Igor’ expression switch, which can be hooked up to remotely control either the resonant filter overtone, or the tremolo. An external CV signal can be used to control the range of the LFO. There’s also a ‘Hi/lo’ switch at the back which can control the overtone range and intensity.

It’s a remarkable fuzz pedal, capable of some truly ferocious, vicious and punky sci-fi synth guitar madness. If you’re after a transparent overdrive, you’re probably in the wrong place here. If you’re a Sigue Sigue Sputnik fan, however, you’ll be thrilled! I love it. I’ve not tried it with a delay yet, but I’m anticipating the results being thrilling, and I can imagine it multitracking very well indeed.
