An OX Stomp Rig is a complete sound with cabinet, mics, room ambience, and multiple effects. OX Stomp's knobs and switches control the Rig that is currently active. OX Stomp can load six Rigs with the Rig knob. Rigs can also be recalled from the footswitches, and assigned to an active footswitch position with the Rig knob or the UAFX Control app.

Output Controls the level of the pedal output. Note that to optimize the sonic quality of OX Stomp's extensive interactivity between its complex modeling components, the output level is lower than other UAFX pedals. Typically, the output level will match the input level between 3 o'clock and maximum. However, the level and panning of each individual mic also affects the overall output volume.
