DRIVE

Turn this switch up to activate the Overdrive mode. This function is foot-switchable.

TREBLE

Controls the amount of treble in your tone.

MASTER

Controls the volume and break-up of the power section of the amplifier.

STANDBY SWITCH

This turns on the high voltage to the tubes. The tubes should warm up for at least one minute before
turning standby switch to ON. Be sure that the Volume control is set to a reasonable position before
switching the amplifier to ON as this amplifier can be very loud! For short breaks (5 minutes or less),
using the standby switch will increase tube life.

PILOT LIGHT

This LED shows that AC Mains voltage is flowing to the amplifier.

POWER SWITCH

Turns on AC power to the amplifier. The Power switch should be turned on, and the pilot light should
be lit for 1 minute before turning the standby switch to ON.
