The Three-Knob Layout: True to the series name, the interface features exactly three essential knobs to sculpt your sound:
Volume: Controls the overall output of the effect. It has enough available headroom to act as a clean volume boost when engaged.
Rate: Adjusts the speed of the modulation LFO, ranging from an ultra-slow, ambient sweep to high-speed warbles.
Depth: Regulates the intensity and width of the pitch modulation, shifting from a transparent widening effect to heavy, seasick waves.
The "Vibe" Toggle Switch: Flipping this onboard toggle changes the entire architecture of the circuit. It completely removes the dry guitar signal from the output, transforming the lush, ensemble chorus effect into a true, pitch-bending vibrato.
Solid Utility Specs: Features standard top-mounted input/output jacks, a durable metal chassis, and runs on a standard center-negative 9V DC power supply drawing 70mA.
If you love no-nonsense pedal design without a million hidden secondary sub-menus, it's a fantastic, reliable board staple.
