EA Tremolo Kit

This kit includes all of the parts needed to build the EA Tremolo GuitarPCB  project. This is a long-time DIY favorite because it sounds wonderful! Originally published as a project in Electronics Australia magazine back in the late 60’s, this circuit is tried and true. This version includes some added bells and whistles, including a switchable boost feature, bi-color LED to show if the circuit is on, and another LED which flashes to the rate of the effect.


This kit includes a 125B or 1590BB enclosure and black Davies 1900h-style knobs. This kit is a pretty tight fit in a 125B, so we recommend the 1590BB option, especially if you are new to pedal building.


All of our kits include a jack for a DC power adapter but no battery snap. If you wish to add a battery snap, please add a battery snap kit to your cart in addition to the pedal kit. Please see what is provided in a kit? in our FAQ for more details of what is included and what you will need to provide to complete the project.
