The Push and Fat switches function as follows:

3-Way Fat switch

  • Fat (up)
  • Normal (middle)
  • Thick (down)

*Fat switch alters lower mids.

3-Way Push (Level) switch

  • Sweet (up)
  • Push (middle)
  • Low (down)

*The Push switch effect is similar to a variable wattage selector on an amp.

Example: in low mode the pedal behaves like a 50 watt head—pissed off, more focused attack, etc. In Push mode (maximum output) it acts like a 100 watt head—smoother, more low end authority, etc. And Sweet is the sweet spot in the middle.

*So to sum it up the Push switch, aside from giving total control of the pedal output (coupled with the Level control) also effects the voicing, too.

Remote Boost jack:

*Any simple latching ON/OFF footswitch will work here.

Pedal must be engaged for this to function (Drive 1 or Drive 2 must be on). The Remote Boost jack works in conjunction with the 3-Way Level switch. When the Remote Boost is engaged the pedal is operating in Push mode (max output). When disengaged it defaults to wherever the Push switch is set. This allows the player to choose the amount of boost needed.

The XXL-Boost v.2 ships with a JJ 12AX7 tube.
