(1) The POWER switch is used to turn the power of the BUGERA amplier on
ando.
(2) The STANDBY switch allows you to place the amp in STANDBY mode
(OFFposition). This way the amp is idle, but the operational temperature of
the valves is maintained (POWER switch turned on). When the switch is set
to its ON position the amplier is activated.
 ATTENTION!
TO AVOID DAMAGE TO YOUR AMP, NEVER USE THE BUGERA VALVE
AMPLIFIER WITHOUT A LOUDSPEAKER CONNECTED!
(3) The CHANNEL push button switches between the CLEAN and the
LEADchannel.
◊ You can also activate both channels with the supplied footswitch.
Refer to “Footswitch” for details.

LEADchannel.

in the LEAD channel. The provided footswitch activates the REVERB eect
(seeChapter “Footswitch”).

CLEAN channel.
(7) This REVERB rotary knob adjusts the eect level of the built-in REVERB in
the CLEAN channel. The provided footswitch activates the REVERB eect

(8) The PRESENCE rotary knob changes the tone of the amplier in the upper
frequencies. This emphasizes the high end and makes the sound crisper.
(9) The passive TREBLE control adjusts the upper frequency range.
(10) The passive MID control adjusts the middle frequency range.
(11) The passive BASS control adjusts the lower frequency range.
(12) This GAIN control species the input level of the LEAD channel. Turn the

Turningthe knob to the right increases the level of the preamplier and,
