Base pedal: David Rolos Twin Peaks Tap Tempo Harmonic Tremolo
Based on David Rolos' Twin Peaks Tap Tempo Harmonic Tremolo, this build recreates an elaborate tremolo circuit that modulates multiple harmonically related frequencies simultaneously — think shimmering, organ-like pulsing rather than simple volume flutter. Tap tempo keeps it locked to your playing.
