INPUTS
There are two choices of instrument input. These are marked Input 1 and Input 2. Input 1 is the 'normal'
input. Input 2 is a 'bright' input which is better suited to clean/acoustic applications.
GAIN 1 & GAIN 2
Each input feeds both gain stages. Gain 1 is bright while Gain 2 is thicker and richer in sound, giving classic
vintage rock tones.These are cascaded together, allowing a wide variety of sounds.
BASS, MIDDLE, TREBLE
The Bass,Treble and Middle tone controls are a traditional passive guitar tone circuit and as such are an
interactive set of tone controls.This type of circuit provides the best overall character for the guitar, giving
a classic, vintage, full-bodied guitar tone. Note that these controls have a greater effect with higher gain
settings.
PRESENCE
Set fully clockwise, this control has no effect on the sound.Turned anti-clockwise, it takes the extreme top-
end out.
MASTER VOLUME
This sets the overall volume level of the amplifier.
STANDBY BUTTON
This puts the amplifier into a STANDBY condition keeping the tubes warmed up and ready for use as soon
as it is disengaged.This button lights blue when STANDBY is disengaged, i.e. when the output stage of the
VU
VU
amplifier is active. Keep STANDBY engaged for at least 1 minute when powering up the amplifier with the
MAINS BUTTON.The life of the tubes will be extended quite considerably if you do this every time you
use the amplifier.
MAINS BUTTON
This is the main power switch for turning ON/OFF the power from the mains inlet socket to the amplifier.
Always keep the STANDBY button engaged for at least 1 minute after turning the unit on to allow time
for the tubes to warm up.
REAR PANEL FACILITIES
Peacemaker 100 Head (50w model only has two AJUST BIAS controls)
MAINS INLET SOCKET & VOLTAGE SELECTOR
This is the mains power inlet to the amplifier. Make sure that the voltage selector dial is set to match the
local voltage supply.
Located above and below the socket are a slow blow and quick blow fuse. If either fuse needs replacing
make sure to use the correct rating and type as marked on the rear panel of the unit.
EFFECTS SEND
This is the jack connection to your effects device from the amplifier.
EFFECTS RETURN
This is the jack connection from your effects device back into the amplifier.
CHARACTER SWITCH
This switch inserts two tubes into the signal path, giving a very different character to the sound. Switched
out (up) yields a classic amplifier with a character of old. Switched in (down) results in a modern, high-gain
sound, but with soul and a unique flavour of its own!
ADJUST BIAS 1, 2, 3, 4 CONTROLS
Allow the bias settings of the tubes to be altered. For more details read the following section entitled
'Tube Guidelines'.
TRIODE / PENTODE SELECTOR SWITCH
Set to pentode will give more grit due to additional third harmonic distortion.
The triode setting yields less power and a smoother distortion - far more musical but much quieter.
BIAS METER SELECTOR
When set to 'audio' the front panel VU meter will indicate the output level of the power stage of the
amplifier. Set the dial to 1, 2, 3, 4 to set the biasing of the corresponding numbered valve.
