1. MAINS
Mains power ON/OFF switch.
2. STANDBY
STANDBY is used in conjuncon
with the MAINS power switch (Front
Panel Funcon #1) to ‘warm up’ the
amplier before use and to prolong
the life of the output valves. When
powering up, always switch MAINS
power on rst, leaving the STANDBY
switch in the ‘standby’ posion. This
allows the applicaon of the voltage
required to heat the valves to their
correct operang temperature. Aer
approximately two minutes the valves
will have reached the correct operang
temperature and the amplier can be
engaged by switching MAINS power
ON.
Note: In order to prolong valve life, always
set the STANDBY switch to the ‘standby’
posion when turning the amplier sound
on and o during breaks in performance.
Also, upon full power down, always put the
amplier in ‘standby’ prior to switching o
the MAINS power.
3. INDICATOR
The power indicator will light when the
amplier’s mains power is switched on
and will be unlit when the mains power is
switched o.
4. SPEED
Controls the speed at which the
‘tremelo’ eect oscillates.
5. INTENSITY
Controls the depth of the ‘tremelo’
eect’s oscillaon.
Note: ‘Tremelo’ will only work when playing
through Channel 2.
6. PRESENCE
Controls the overall amount of higher
frequency content in your sound. Turn
clockwise to add crispness and bite for a
more cung tone. Presence is a power-
stage funcon and acts independently of
the preamp EQ controls.
7. BASS
Controls the amount of lower frequency
content, or boom-end, in your sound.
Turning clockwise will increase the
boom-end giving a fuller tone.
8. MIDDLE
Controls the middle frequency content
of your sound. Turning clockwise adds
girth. Turning anclockwise reduces
