Project Summary
An all-analog tremolo featuring six knobs for fine control over every aspect of the waveform.

Legacy PCB

Designed for the 1590B enclosure with side-mounted jacks, which some builders prefer. Bypass PCB (optional) sold separately.

Project overview

The Luna Tremolo is a modified version of the 4ms Tremulus Lune, a classic DIY optical tremolo circuit that allows fine-grained control over the LFO shape.

Several of the Tremulus Lune circuit’s optional modifications are included standard in this PCB, including the Symmetry control as well as an external gain adjustment control so you can achieve unity volume with any setting.

The Luna adds a few improvements to the original design, including an input buffer to reduce noise and some added filtering to counteract ticking from the LFO. All of the knobs are located on the front panel in an efficient layout that easily fits in a 1590B enclosure.
