Envelope filter with adjustable threshold.
This pedal takes simplicity to a whole new level. Use the one knob to dial in the sensitivity threshold and the pedal will be set and ready to go. The Auto-Wah was designed to be signal sensitive, so it adjusts to every nuance of your playing style. Use the ModTone Auto-Wah to get that classic '70s vibe or use it to spice up your solos.
