for level adjustment to match volumes)
• Foot selectable boost switch with tube-driven boost (boosts clean channel and both
volume/gain controls on crunch channel). Boost is adjustable from the front panel for
approximately 0 - 20db boost.

• 3 x 1/4" jacks tied to the footswitch controller for controlling through tip to ground

engaged.

for quick overall volume adjustment.
