HARMONIC TREMOLO - DUAL BAND MODULATOR

The Harmonic Tremolo is an analog MOSFET adaptation of the beautifully elusive Fender Brownface era Harmonic Vibrato circuit. Fender’s “Vibrato” is actually a Tremolo effect (modulation of volume or amplitude). However, in the early 60's, Leo Fender developed a much more interesting version of Tremolo where the signal was split into treble and bass bands, and these two paths were amplitude modulated (tremolo) with out-of-phase LFOs.
