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 features a bi-color LED that blinks to the rate of the effect. It blinks red when the circuit is on, and green when the circuit is on.


This kit includes a 125B enclosure and black Davies 1900h-style knobs. Per the build document, using a 3PDT board is not recommended with this kit due to the blinking status LED feature, and therefore this kit does not include one.


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. If you do not add a battery snap to your order, the kit may (or may not) be drilled such that a battery cannot be accommodated in the enclosure.


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.
