Controls

• Volume – Controls the master output volume

• Drive– Controls the amount of signal gain

• EQ – Lowpass filter that removes higher frequencies

• Air – Similar to amplifier presence control

• Boost – Controls the level of boost (when active)

• Headroom (Toggle switch) – Toggles between three different “wattage” settings (25W, 50W, 100W)

• Drive (Footswitch) – Toggles Drive stage on/off

• Boost (Footswitch) – Toggles the Boost stage on/off

Specifications

• Designed for a 125B enclosure with top-mounted jacks
