EA Tremolo

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.

Trem , but not as we know it 4 product stars
"Easy to build kit , set the voltage as required to 4.5 volts and it gives an unusual trem . It works but not like an opt. bias version in an amp. Can t seem to get that effect as on the song Bang Bang by Nancy Sinatra ! Will try an optical version next !!" Clive Kay - 04 October 2020
