Front Panel
1
Master Drive knob
: controls signal level to
tank send
output (see rear panel: 5), and how hard the
unit’s amplification/distortion stage is driven.
2
Input gain switch
: When switched
up
, input signal is attenuated by around 18dB, so the
amplification/distortion stage is driven at lower volume. When switched
down
, the
amplification/distortion stage is driven at full volume.
3
Amplifier knob
: controls how much of the amplified/distorted signal is passed to the unit’s output
mix.
4
Reverb bass/treble cut switches
: these switches allow you to filter the signal coming into the unit
at the
tank return
input (see rear panel: 7), optionally cutting low and high frequencies from that
signal.
5
Reverb level
: this knob controls the level of the reverb signal passed to the unit’s output mix.
6
Original level
: this knob controls the level of original, unaffected, signal passed to the unit’s output
mix.
7
Effect switch
: when
up
, the unit’s reverb and amplification/distortion stages are muted.
8
Master Out knob
: controls the overall level of the unit’s output mix.
9
Triode/Pentode valve mode switch
: selects the unit’s amplification/distortion mode.
10
Standby/mains switch
: when
up
, unit is in standby mode. Always set to
standby
(up) when
plugging in and switching on the unit at the rear panel. Only set the
standby/mains
switch to the
mains
position 30 seconds or so after turning on the mains: this will give the valves in the unit time to
warm up.
11
Mute button
: this button mutes the output of the channel. This is very useful for avoiding potentially
very loud “clicks” when changing settings. Always press the mute switch and hold it in while
changing
valve mode
, turning
effect
on/off, or changing the
input gain
setting.
