Many of the effects are in stereo, so best results are achieved with stereo amplification, though a mono output is available via the left output jack. Because guitar output levels can vary wildly, there's an input trim pot and peak indicator LED.
When the pedal is used as a volume control, it can be assigned to different positions in the effects chain, with the minimum volume position set to give anything between off and fully on. In parameter control mode, the pedal may be assigned to: Wah Wah; Distortion Drive; Compressor Sense; Chorus Depth; Pitch Shift Balance; Wah Range; Equaliser High gain; Amp Simulator Mix Balance; Delay Mix.
A chunky footswitch is used for effects selection, the effects being grouped into four banks of five programs. Pushing and holding the footswitch switches from one bank to the next; pushing briefly on the switch steps through the effects in the bank. The footswitch also has a hidden switching function which can be used to turn a selected effects block (or, in some cases, blocks) on or off.
