10. Voice
The 4-position Voice control operates as a preamplifier tone control shift, while also
controlling the power amplifier damping and gain. In this way it allows the amplifier
to follow the evolution of 100W guitar amplifier design.
The four modes are described in the table below.
Mode Tone Control Character Power Amplifier Character Description
1
Early ’50s
Hi Damping / Lo Gain

100 Watt head
Higher Gain
maximum so the amplifier is really
crunchy. The tone is like a later

11. Presence
This control operates on the power amplifier and adds higher frequencies that
enable the guitar to ‘cut through’ at higher volumes.
Master
12. Power Indicator Light
The power indicator will light when the amplifier is switched on.
13. Standby
This switch applies the H.T. (High Tension) voltage required to produce sound.
Always turn this switch on at least 30 seconds after the Power switch (14) and off at
least 30 seconds before the Power switch. During short breaks in playing use just
this switch to turn ‘off’ and ‘on’ the amplifier’s output.
