CONTROLS

Knifeswitch; Power to the unit is turned on by throwing the knife switch manually. (Do this before you

start playing). In ‘power off’ (up) position no power is drawn from the battery.

OVERTONE; Turning this knob changes the harmonic overtone of the sound. The distortion circuit has

a kind of inherent noise gate-type of effect built in to it, which means the unit is totally silent between

notes.

VOLUME; This adjusts output volume, while the ‘INPUT’ meter monitors your input signal.

MOD.; This switches on a modulation control, which has the effect of moving the OVERTONE control

backwards and forwards (this knob now controls modulation width).

RATE; This controls the MOD oscillator speed, its frequency shown by the flashing white and red

meter backlights.

ON/OFF; This footswitch puts the Dr Freakenstein Fuzz into the circuit, or bypasses it (with hard-wired

true bypass).

HI/LO; On the back panel, this pushbutton switch changes the effect from a low intensity to a high

intensity overtone.

IGOR

Dr Freakenstein’s assistant is Igor. It’s a pressure-sensitive controller, which, when plugged into the

IGOR OVERTONE input on the back panel, controls ‘OVERTONE’. Or plug it into the IGOR MOD.

RANGE input and Igor controls the bias of the modulation oscillator; the harder you press, the higher

the range of the sweep (with the ‘OVERTONE’ knob now acting as low ‘end-stop’). Use it with your foot

or hand.

It has two pressure sensitivities; use it hard side up and it requires a firm press. Flip it over and use it

rubber side up and it only needs a very light press to work – and can be used by hand this way
