Fuzz Dog Throb Tremolo v4
Mark M's modified Schaller Tremolo circuit. A worthy update of a chassic chopper that refines the fought edges and makes it, well... pretty super.
From soft, subtle wobble to outright chop, this is a pretty versatile circuit.
The speed range has been increased with the addition of a switch to flip between Fast and Slow modes.
The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.
Note: the flashing bypass indicator LED function is not compatible with the OptoPuss bypass system.
Enclosure (pre-drilled) is available as an option with full kits, and can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included.
Builds are only available with full kits including enclosure and vertical-mount pots.
