INPUT SECTION
1. INPUT JACK SOCKET
As the name suggests, this jack socket is used to connect your guitar into the amplifier. It is
important to remember that the use of high quality cables is of paramount importance to obtain
the best and most consistent performance. Although good cables can be relatively expensive, it
is without doubt a very worthwhile investment. We recommend Vox cables. Please contact your
dealer if you need assistance selecting a high-quality cable.
2. CHANNEL SELECT SWITCH
The front panel toggle switch marked CHANNEL 1/CHANNEL 2 is used to select which channel
is going to be selected for use: -
CHANNEL 1 is primarily the CLEAN/CRUNCH sounding channel & CHANNEL 2 is for much
heavier and overdriven sounds.
The rear mounted FOOTSWITCH jack socket is also available to connect the foot operated
switching box (VOX VF002) to allow remote channel switching operation.
REMEMBER! To use the Footswitch function the Front Panel, the toggle Switch MUST be set to the CHANNEL
2 position. The associated Channel LED (Green for Ch1, Red for Ch2) will illuminate when each
channel is selected.
CHANNEL 1 SECTION
3. GAIN CONTROL
This control regulates the amount of signal amplification that is generated in the Channel 1
preamplifier circuit, and as such sets the basic tonal qualities of the channel. The circuit design of
Channel 1 is based on the Top Boost channel of the historic VOX AC30. Therefore the basic
sound of this channel is classic VOX through and through. But by some subtle changes and
tweaks this channel will also give you some serious classic rock Crunch. Although different types
of guitars and pick-ups will give differing output levels and thus amp settings will vary between
different guitars, then generally the rule of thumb is that cleaner sounds are going to be between
Off (naturally!) and about 2 o’clock position of the knob. After that the channel preamp will slowly
start to go into crunchy distortion, with the maximum distortion at Full (of course!). Although this
channel is not seriously high gain (we’ve left that for channel 2) the distortion level can be seri-
ously satisfying.
