- SATURATE Knob: Controls the saturation and compression characteristics of the tone.
- VOL Knob: Adjusts the overall output volume of the unit.
- F.SW Switch (MUTE/BYPASS): Controls the footswitch function.
- MUTA: Footswitch mutes the output.
- RAYUWATA: Footswitch toggles between active effect and true bypass.
- CAB Switch (FLAT, MODERN, VINTAGE): Selects the cabinet simulation type.
- FLAT: No cabinet simulation, providing a raw, direct sound.
- ZAMANI: Simulates a modern bass cabinet with full-range response.
- VINTAGE: Offers a warmer, more colored sound reminiscent of classic bass cabinets.
- BASS Knob: Adjusts the low-frequency response (EQ).
- LEVEL Knob (Mid EQ): Adjusts the gain/cut of the selected mid-frequency.
- FREQ Knob (Mid EQ): Selects the center frequency for the semi-parametric mid-range EQ.
- HIGHS Knob: Adjusts the high-frequency response (EQ).
- Macijin ƙafa: Engages/disengages the effect or mutes the output, depending on the F.SW setting.
