Fairly simple but nicely effective tremolo kit.
A lot of trems use expensive optocouplers or require some fiddling with LED/LDR combinations to make them work, but this does all the magic with a clever combination of transistors.
Rate, Depth and Volume controls, and the LED flashes to indicate the rate. Bonus!
This latest version of the PCB is set up for vertical-mount pots to make it a really quick and easy build. The vertical mount pots have round shafts, so take that into consideration when choosing your knobs - you'll need a grub-screw fixing. You can go for 'normal' pots with splined shafts and wire them or use header pins to attach them.
Kit includes: PCB, all components, hook-up wire, 3PDT footswitch for true bypass, jack sockets, DC socket, battery snap, LED. Enclosure (pre-drilled) is optional and will take a battery. Does not include knobs.
PCB size: 50 x 25mm
Knobs required: 3
Direct-Connect compatible (4-way)
Check Specials for powder-coated enclosure availability.
