Front Panel
1. Input
Plug your guitar in here. Always use a good quality screened guitar lead.
2. Gain
When the Overdrive is not engaged, low settings counter clockwise (CCW), will
deliver a clean sound. As the Gain control is increased clockwise (CW) the sound
will move from clean into break-up, until at its maximum position, a full crunch tone
is reached.
When the Overdrive is engaged, the Gain control adjusts the amount of overdrive
or distortion. Low settings, counter clockwise, will deliver a clean sound on the
edge of break-up. As the Gain control is increased CW the sound will become
more overdriven moving through crunch tones until, at its maximum position, a full
distorted lead tone is reached.
3. Overdrive Select
Press this switch to engage the Overdrive. The built-in Overdrive ranges from a
dynamic crunch to a tight high-gain overdrive.
NOTE: This switch must be pressed to allow the use of a compatible footswitch to
engage the Overdrive.
4. ISF (Infinite Shape Feature)
The patented ISF control allows you to choose the exact
tonal signature you prefer. Fully counter clockwise has
a more American characteristic with a tight bottom-end
and accentuated presence and treble. Fully clockwise
has a British characteristic adding more low-mid body
and has a softer more 'woody' sound.
5. Reverb
The Reverb control sets the overall level of the reverb
effect. With the control fully counter clockwise there will be no reverb. Turning the
control clockwise will increase the amount of reverb.
6. Master Volume
This controls the output volume of the amplifier. Turning it clockwise increases the
volume, pushing the Class A power stage into saturation.
7. Power Indicator Light
The power indicator will light when the amplifier is switched on.
8. Standby
This switch enables the operation of the speaker output. For silent recording or
practice this switch should be put in the standby position. This will disable the
speaker output, but the emulated output will continue to work.

9. Power
This switch is used to turn the amplifier on and off. You should always turn this
switch on before turning on the Standby switch (8).
Rear Panel
1. Mains Fuse
The value of the Mains Fuse is specified on the rear panel. Never use a fuse of the
incorrect value or attempt to bypass it.
2. Mains Input
The supplied detachable mains lead is connected here. The lead should only
be connected to a power outlet that is compatible with the voltage, power and
frequency requirements stated on the rear panel. If in doubt get advice from a
qualified technician.
3. H.T. Fuse
The value of the H.T. Fuse is specified on the rear panel. Never use a fuse of the
incorrect value or attempt to bypass it.
4. Speaker Outputs
The output marked '1x16 Ohm' is for the connection of a single 16 Ohm extension
speaker cabinet (or the internal loudspeaker of the Studio 10 KT88 combo).
The outputs marked '1x8 Ohm or 2x16 Ohm' are for the connection of either a single
8 Ohm extension cabinet or two 16 Ohm cabinets. Also, the internal loudspeaker
of the Studio 10 KT88 combo can be plugged in here if it is used with a 16 Ohm
extension cabinet. See table below.

WARNING: The output marked '1x16 Ohm' should never be used at the same
time as any of the outputs marked '1x8 Ohm or 2x16 Ohm'. Failure to correctly
match the impedance of the amplifier and speakers will damage the amplifier.
5. Speaker Emulated Output
This output emulates the tonal characteristics of a guitar speaker cabinet and
provides a natural valve overdrive tone for connection to a recording device or
mixing desk. Always use a good quality screened lead.
IMPORTANT NOTE: Always use a stereo jack lead when using this output, as this
will not function with a mono jack lead.
