EA Tremolo

From the vendor

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! The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. 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.
