Gurgle & Moan

The Subdecay Gurgle & Moan is an analog envelope filter effects pedal designed for shaping dynamic filter sweeps. This prototype filter stompbox includes frequency, resonance, shape, and depth controls to modify filter response and cutoff behavior. The resonance control can drive the circuit into self-oscillation at higher settings. The unit has a true bypass footswitch and status LED, and is powered by either a 9V battery or a standard Boss-style 9V DC barrel adapter. This prototype effect pedal features a plain enclosure with control functions labeled on a rear sticker. **Features:** - Analog envelope filter effects pedal - Shape control for selecting bandpass or lowpass filter modes - Resonance control to accentuate or drive filter cutoff into oscillation - Depth and frequency controls for dynamic filter response - Powered by 9V battery or Boss-style DC power adapter - True bypass footswitch for signal integrity - LED indicator Category: envelope filter pedal, Subdecay effects pedal, analog filter stompbox
