Botto-Wah

Drive, Modulation

A robotic auto-wah with aggressive lo-fi crush. Synth-like sweeps with digital bite.

An LFO drives a wah filter across a wide frequency range while a stepped, sample-rate–reduced crush adds hard, mechanical texture. Routing lets you place the crush before or after the filter for different flavors of grit.

Knob controls:

  • Rate – LFO speed (0.05–8 Hz).
  • Wah Range – Filter sweep range (200–4000 Hz).
  • Crush – Robotic depth (1–16 steps).

Footswitch controls:

  • Short press – Cycle LFO shape (triangle → sine → square).
  • Long press – Toggle crush routing (pre ↔ post).
