From the vendor

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. If you want the PCB without parts there's a link for that at the bottom of the page. Partial kit: PCB, all board-mounted components, pots. Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED. 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. Please choose appropriate knobs.
