FRONT PANEL CONTROLS AND THEIR RESPECTIVE FUNCTIONS:
BASS, MIDDLE, TREBLE, PRESENCE (WHERE FITTED)
This is the equalisation part of the amplifier, and these controls shape the overall response of the
amplifier. Balancing these controls can provide you with a large range of tones from which to
work. All the controls are interactive (moving one will alter the way the others function) and you
should spend some time experimenting to find out what's available.
On some models there is an EQ button fitted, this changes the values in the equalisation circuit
from a typical British style EQ to a typical American style EQ.
REVERB
Where fitted the Reverb control allows the user to vary the amount of reverberation applied to the
signal before being fed to the power amplifier. Reverb is used to add "space " around the sound
and enhances the tone of the amplifier.
MASTERS
The Master Volume controls the final amount of signal that is fed to the power amp and therefore
the overall volume of the amplifier. The Master works in conjunction with the Gain control as
follows. For clean tones the Master needs to be fully up, controlling the overall volume with the
Gain control. For distortion tones at controllable levels, turn the Master down and the Gain up.
Varying the Gain will control the amount of distortion and the Master will control the overall level
of the sound. Some models have dual master volumes that work in conjunction with the gain
controls it therefore follows that master 1 will be used with gain 1 and so on
EFFECTS LOOP (WHERE FITTED)
The FX sockets on the front or rear panel are 1/4" jack connectors which accommodate both the
Signal send to the effects pedal or rack, and the Return back from the effects unit to the amplifier.
It is therefore necessary to use either a stereo cable terminated in two mono 1/4" jack plugs at one
end (which connects to the FX sockets on the amplifier) and a pair of mono 1/4" jack plugs at the
other (which connect to the input and output of the effects unit Or alternatively two mono jack to
jack leads.
STEALTH SWITCH (WHERE FITTED)
The Stealth switch is located on the front the amplifier. When switched into Stealth mode,
the output of the amplifier is reduced , enabling the full range of tones to be achieved at lower
overall volume levels in recording applications.
