Using the Pedal

Level Knob

Controls the overall output level of MR JAX. Typically set to unity gain when the pedal is engaged and dis-engaged. This is a good starting point for the Gain Staging to add enough volume between each stage.

Gain Knob

Controls the amount of breakup/distortion. Set between 9 o'clock and noon for light to aggressive overdrive, anything above noon starts to get into distortion territory.

Tone Knob

Controls the amount of high end roll off. Set to noon for a very neutral sound, turning the knob counter-clockwise will remove more high end as well begin to shape your tone into more overdrive territory. Turning the knob clockwise will add more high end as well begin to shape your tone into more distortion territory.

Soft-Click Bypass Switch

Short press to engage and dis-engage MR JAX. While the pedal is engaged, long press (hold for at least a half of a second and release) to cycle through each Gain Stage. While the pedal is engaged, double tap to engage the Mid Boost. While the pedal is dis-engaged, long press to cue up any desired gain stage, press again to engage MR JAX with the cue'd up gain stage.

Multi-Colored Indicating LED

LED off means MR JAX is bypassed. A solid LED color means MR JAX is engaged, the color of the LED indicates which Gain Stage is active (see Gain Staging for more info). While MR JAX is dis-engaged, a slow flash indicates the cue'd up gain stage. While MR JAX is engaged, a rapid flash indicates the Mid Boost is engaged.
