1. INPUT jack
Use a good quality guitar cable (i.e. one that’s
screened/shielded) to plug your guitar in here.
2. Clean Channel GAIN control
The Clean Channel has two selectable modes,
Clean & Crunch. When in Clean mode, the Gain
control takes you from clean, bell-like tones to a
mild, bluesy distortion at high settings. When in
Crunch mode, this control takes you from a creamy,
‘70s crunch, to the roar of a hot-rodded JCM800
and all points in-between.
3. CLEAN / CRUNCH Select
Push switch to select either clean or crunch
sounds on the normal channel (push in for Crunch).
4. Clean Channel BASS control
Turning up the Bass control will add warmth and
low-end depth to your clean sound. The Bass control
can be used in conjunction with the FDD switch (21) to
produce deep sounding, valve-like clean tones that
are well defined yet still full and round.
5. Clean Channel MIDDLE control
Adjusting the middle frequencies in your Clean
Channel will vary the amount of body to your sound.
Attenuating (decreasing) the middle by turning this
control anticlockwise will yield a more hollow sound
with the bass and treble frequencies appearing to be
more accentuated. Conversely, increasing the
middle will add body to the Clean Channel’s sound.
6. Clean Channel TREBLE control
Increasing the Treble will make your clean sounds
brighter and more cutting, turning it down will
decrease your tones edge and make it sound softer
as a result.
7. CHANNEL SELECT switch
This push switch allows you to change between
the amp’s two channels, Clean and Overdrive, via
the front panel. When this switch is ‘out’ the Clean
Channel is engaged, pushing it ‘in’ switches to the
Overdrive Channel. Channel switching can also be
done via the included two-way footswitch (when the
footswitch is connected the CHANNEL SELECT
switch is not functional).
Note: When the Overdrive Channel is selected,
the OD LED (8) will light up red.
8. OD LED
When illuminated, this LED indicates that the
Overdrive Channel has been selected by either the
Channel Select switch (7) or the supplied two-way
footswitch.
9. Overdrive Channel GAIN control
Turning up the Gain control will increase the
amount of preamp distortion generated in the
Overdrive Channel. Low Gain control settings will
produce classic rock and blues tones. Crank this
control for fat and aggressive sounds that are
perfect for soloing or hard rock and nu-metal riffing.
10. OD1 / OD2 Select
OD1 mode (switch out) offers more distortion than
most amps, OD2 (switch in) takes you to the next
level and is definitely not for the faint-hearted!
11. Overdrive Channel BASS control
Turning up this control will add extra low-end
‘thump’ to high gain riffs and a warm, natural
sounding depth to lower gain crunch tones. Using
the Bass control in conjunction with the FDD switch
(21) will allow you to dial in the exact amount of low-
end ‘thump’ and tightness you are looking for.
12. Overdrive Channel MIDDLE control
Adjusting the middle frequencies in your Overdrive
Channel will vary the amount of body to your sound.
Attenuating (decreasing) the middle by turning this
control anticlockwise will yield a more hollow sound
with the bass and treble frequencies appearing to be
more accentuated. Conversely, increasing the
middle will add body to the Overdrive Channel’s
sound.

13. Overdrive Channel TREBLE control
This important knob controls the aggressive top-
end ‘sizzle’ you have on high gain sounds and the
‘cut’ and definition of lower gain crunch tones.
Experimenting with this control will help you to
dial in your own signature tones on your amp.
14. Overdrive Channel CONTOUR control
This highly effective tone control works by
radically modifying the mid-range (body) of your
sound. The tone can vary from traditional and
woody sounding (control set at 0), to balls-to-the-
wall (control set midway), to aggressive, ‘scooped’
and modern (turned up to 10) and all points in-
between.
15. Overdrive Channel VOLUME control
This control adjusts the volume of the Overdrive
Channel. The louder you turn up this channel, the
‘looser’ your amp will sound and feel – especially
with the FDD switch (21) engaged. This behaviour
is exactly what a good all-valve amplifier does
and is a result of our proprietary FDD circuitry.
16. Digital FX PRESET / ADJUST control
This control serves a dual purpose. Not only
does it allow you to select one of the four types of
effects on offer (Chorus / Delay (CHR/DLY),
Delay (DLY), Chorus (CHR) or Flange (FLG)), it
also allows you to adjust a parameter as you
sweep it through each of the four effect segments.
The parameter you can adjust for each of the four
effect segments is shown below:
ENGLISH
3 4
Chorus
and Delay
(CHR/DLY)
Effect DescriptionAdjustable Parameter
Delay Time
(from short to long as you turn the
Preset/Adjust control clockwise
through the CHR/DLY segment)
This multi-effect combines a lush, fixed speed
Chorus with a variable time Delay.
Delay
(DLY)
Delay Time
(from short to long as you turn the
Preset/Adjust control clockwise
through the DLY segment)
Short Delay Times will have less repeats for
‘groovy’ surf and rockabilly tones. Increasing the
Delay Time increases the number of repeats for a
much more atmospheric, ‘stadium’ effect.
Chorus
(CHR)
Speed
(from slow to fast as you turn the
Preset/Adjust control clockwise
through the CHR segment)
At slow Speeds a mellow, Phase-like sweep
occurs. As the Speed is increased a more
traditional chorus effect is heard. At maximum
Speed, a psychedelic vibrato results.
Flange
(FLG)
Speed
(from slow to fast as you turn the
Preset/Adjust control clockwise
through the FLG segment)
At slow Speed settings the amount of regeneration
is increased for huge ‘jet engine-like’ sweeps. As the
speed is increased the regeneration decreases to
produce a lush, natural sounding Flange effect. When
the Speed is maxed out, a fast vibrato results.
