Rainger FX Dr FREAKENSTEIN CHOP FUZZ User Manual

Dr FREAKENSTEIN CHOP FUZZ - USER MANUAL
Congratulations on buying the Dr Freakenstein Chop Fuzz! This is the most extreme distortion effect to
emerge from the laboratory of Rainger FX – coupled with modulation and hard squarewave ('chop')
tremolo, and we hope you have serious fun with it.

CONTROLS

Knifeswitch; Power to the unit is turned on by throwing the knife switch manually. (Do this when
you're setting up). In 'power off' (up) position no power is drawn from the battery.
ON/OFF; This footswitch puts the Chop Fuzz into the circuit, or bypasses it (with hard-wired true
bypass).
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 'eye' meter monitors your input signal.
MOD. ON/OFF; This switches on a modulation control, which has the effect of moving the OVERTONE
control backwards and forwards (this knob now controls modulation width).
LFO RATE; This controls the MOD oscillator speed, its frequency shown by the throbbing white meter
backlight.
CHOP RATE; This controls the speed of the chop tremolo, shown visually by the red strobing LEDs
either side of the meter.
CHOP; On the top end panel, this PCB switch engages the 'chop' tremolo. BTW the MOD ON/OFF
switch needs to be on (down) for the CHOP switch to work.
HI/LO; On the top end 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 input on the top end panel, controls either OVERTONE, or the chop effect – depending on how
the pedal is configured. Igor is dual sensitivity; use it shiny side up on a hard stage with shoes, or
rubber side up if you're sitting down or barefoot (difference in sensitivities will be less noticeable if
you're using it on a carpet instead of hard floor). Or use it with your hand!
