Mode A is set for classic soft clipped overdrive, but with extra bass and gain available on top
Mode B is less compressed with more volume, and capable of clear, powerful output for slamming an amp
Mode C is hard clipped drive, capable of going into distorted and fuzzy textures at higher gain settings
PUNCH controls the amount of gain and drive in the circuit.
More punch = more crunch
SHAPE refines the frequency response and amount of grit. Think of it as controlling how much “hair” is in the drive
STACKS is a low-pass filter that controls the amount of high-end treble content in the distorted output
The SPEAKER is the overall effected volume. Consider yourself warned – this pedal has a LOT of volume on top (especially in Mode B)
