1. Input
Plug your guitar in here. Always use a good quality screened guitar lead.
Clean Channel
2. Clean Select Switch
Press this switch to select the Clean Channel. When the green LED is on, the Clean
Channel is selected.
3. Clean Volume
This controls the volume of the Clean Channel. Turning it clockwise increases
the volume. At extreme clockwise settings the preamplifer will start to overdrive,
particularly in the ‘British’ mode.
4. Clean Voice Switch
This is a momentary switch that selects between the two clean voices. The
‘American’ setting is very clean and bright but with a solid and tight low end; this
Voice is selected when the Voice LED is unlit. The ‘British’ setting has a looser bass
response with warmer mid-range and is very sensitive to the output level of the guitar
and the player’s dynamics; this Voice is selected when the Voice LED is lit. The EQ
voicing and valve gain structure is completely reconfigured between each voice.
5. Bass
The Bass control adjusts the amount of bass frequencies in your tone. Fully counter
clockwise the sound will be tighter in character. Rotating the control clockwise will
progressively increase the bass response of the channel.
6. Treble
The Treble control allows adjustment of the treble frequencies within the sound. At
low settings (counter clockwise) the sound will be warm and darker in character. As
the Treble control is rotated clockwise the sound will become brighter.
OD 1 (Overdrive 1) Channel
7. OD 1 Select Switch
Press this switch to select the OD 1 Channel. When the yellow LED is on, the OD
1 Channel is selected.
8. OD 1 Gain
The OD 1 Gain control adjusts the amount of the OD 1 Channel’s overdrive or
distortion. Low settings (anti-clockwise) will deliver a clean sound on the edge
of break-up. As the Gain control is increased clockwise the sound will become
more overdriven, moving through crunch tones until, at its maximum position, a full
distorted tone is reached.
9. OD 1 Volume
This control adjusts the overall volume of the OD 1 Channel. Turning it clockwise
increases the volume.
10. OD 1 Voice Switch
This is a momentary switch that selects between the two voices of the OD 1
Channel. When the small yellow LED is unlit, this channel has a ‘classic’ overdrive
voicing. With the yellow LED lit the overdrive sound has a more ‘modern’ voicing,
with a greater bass response and a looser, more aggressive sound due to reduced
power amp damping.
OD 2 (Overdrive 2) Channel
11. OD 2 Select Switch
Press this switch to select the OD 2 Channel. When the red LED is on, the OD 2
Channel is selected.
12. OD 2 Gain
The OD 2 Gain control adjusts the amount of overdrive or distortion in this channel.
With low settings (anti-clockwise) the tone will be mildly overdriven. As the Gain
control is increased clockwise the sound will turn from crunch to a high gain,
saturated lead tone.
13. OD 2 Volume
This controls the overall volume of the OD 2 Channel. Turning it clockwise increases
the volume.
14. OD 2 Voice Switch
This is a momentary switch that selects between the two voices of the OD 2 Channel.
With the small red LED unlit this channel has a ‘classic’ but ‘hot-rodded’ overdrive,
with medium power amp damping. With the red LED lit the overdrive sound has a
more ‘modern’ voicing that includes a strong mid-emphasised pre-overdrive boost,
as well as a looser, more aggressive sound due to reduced power amp damping.
OD 1 and OD 2 EQ
15. Bass
The Bass control adjusts the amount of low-end frequencies in your tone. This amp
has an advanced tone shaping circuit which allows the tone to be varied from tight
and cutting when counter clockwise, to warm and thumping when fully clockwise.
16. Middle
The Middle control adjusts the amount of middle frequencies in your tone. The middle
frequencies are particularly important in setting the amount of ‘body’ your tone has.
With the Middle control set to its minimum position (fully counter clockwise) the sound
will be aggressive and scooped, a tone ideal for aggressive rhythm playing. As the
Middle control is increased (clockwise) the amount of ‘body’ is increased, which is
more suitable for sustained lead guitar tones.
