Throbby

The Basic Audio Throbby is a 70s Fender-style sine wave tremolo. Smooth and subtle at low depth settings, it becomes more square wave-like when cranked for choppy, rhythmic effects.

The Range switch adjusts speed range, while the Level control allows using the Throbby as a boost when depth is set to zero. This dual functionality adds utility to an already useful effect.

Handmade in Philadelphia, capturing the warm pulse of brownface Fender amps.
