Front Panel
1. Input
Plug your guitar in here. Always use a good quality screened guitar lead.
2. Gain
This control adjusts the amount of overdrive or distortion. Due to the sophisticated
design of this amplifier, the effect of this control varies depending on which channel
and voice is selected.
When the Clean Channel is selected, 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 crunch tone is
arrived at.
When the Overdrive Channel is selected, 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 clockwise the sound
will become more overdriven moving through crunch tones until, at its maximum
position, a full distorted lead tone is arrived at.
3. Overdrive Select
Press this switch down to select the Overdrive Channel. When the switch is down
the Overdrive Channel is selected and the corresponding LED will be lit. When the
switch is up the Clean Channel is in operation.
4. Volume
This controls the volume of the Clean and Overdrive Channels. Turning it clockwise
increases the volume.
5. Voice Select
This switches the current channel (Clean or Overdrive) between two voices.
On the Clean channel, with the switch up (LED off) this will produce a tone based
on a classic American clean amplifier - a bright, mid-shaped tone with a rounded
bottom end. With the switch down (LED lit) the preamp circuit is reconfigured to
emulate a classic British tone – crunchy, chimey and dynamically responsive.
With the Overdrive channel selected, the Voice switch up will result in a tight
supercrunch tone. With the Voice switch down, a higher gain tone will be achieved.
6. ISF (Infinite Shape Feature)
The patented ISF control allows you to choose the
exact tonal signature you prefer. Fully CCW has a
more American characteristic with a tight bottom
end and more aggressive middle, and fully CW has a
British characteristic which is more 'woody' and less
aggressive.

7. 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.
Reverb decay times can be adjusted for the Clean and OD channels by connecting
to our Architect deep-editing software.
8. CabRig Switch
The switch enables you to instantly select between one of the three stored CabRig
patches. This will apply to both the Line Out / Phones and the relevant USB output.
CabRig patches can be edited using Architect software. Learn more about Architect

9. CabRig Output - Stereo Line Out / Phones socket
This output provides a stereo un-balanced connection to a recording device or
mixing desk. Always use a good quality screened TRS lead. The stereo jack socket
also accommodates connection of headphones, allowing you to practice silently.
