Tremmatic

The Tremmatic provides optical tremolo with two waveforms—sine and square—selectable via toggle switch. Speed ranges 3Hz to 13Hz with dedicated Depth control and LED speed indicator for visual feedback. Hidden feature: Depth set to zero reveals colorful, powerful MOSFET preamp/booster circuit, adding versatility beyond tremolo. Level control adjusts overall output volume.

Ranges from soft vibe sounds to aggressive chopping effects. Sine wave delivers smooth vintage-style pulsing; square wave produces hard, percussive chop. Compact 70×112×50mm enclosure weighs 0.8kg. Draws minimal 4.5mA at 9V DC.

Handmade in Athens, Greece with true bypass. Compatible with 9V or 12V supplies.
