Tremmatic

This is a handmade optical tremolo pedal designed to deliver a wide range of amplitude modulation effects, from subtle vibe tones to pronounced hard-chopping tremolo. The unit offers a variable LFO rate spanning 3Hz to 13Hz, with both sine and square waveforms selectable via a dedicated toggle switch. Depth control allows adjustment of effect intensity, and when set to zero, the pedal functions as a MOSFET preamp booster. **Features:** - Optical tremolo pedal with adjustable modulation rate (3Hz–13Hz) - Two selectable LFO waveforms: sine and square - Depth control for effect level or use as MOSFET preamp booster - 100% handmade build - True bypass switching for signal integrity - Standard 9V DC power operation
