Detail 01
Brownface/blackface toggle
It selects harmonic tremolo or amplitude-modulation tremolo.

Independent shopping perspective
SurfyTrem V1.1 brings two analog tremolo approaches into a compact pedal. Brownface mode uses harmonic modulation, shifting highs and lows independently for a fluid pulse that changes with playing dynamics. Blackface mode uses amplitude modulation for a more defined rhythmic effect. Intensity and speed controls cover the amount and rate of movement without complicating setup. It has single 1/4-inch input and output connections and can run from a 9V battery or 9V DC adapter.
