FRONT PANEL FUNCTIONS

[1] INPUTS

NORMAL - Input for standard instruments, e.g. guitars with single-coil pickups.
BRIGHT CLEAN - Input for high-output instruments, e.g. guitars with humbucker pickups. This

input has 6dB gain reduction to prevent overload and a filter which compensates guitar cable
losses by boosting the high frequenciesas of 3Khz. (Due to their higher coil impedance,
humbucker pick-ups suffer more from cable losses than single-coils, which may result in lack
of sparkle in the clean sound)

NOTE: The BRIGHT CLEAN input only changes Channel 1, the CLEAN channel, but
does not affect the Channel 2-5, the distortion channels.

[2] VOLUME: Controls the volume levelof Channel 1, the CLEAN channel.
[3] BASS, MID & TREBLE: Classic passive tone controls ofChannel 1.
[4] DRIVE: This DRIVE knob controls the amount of distortion in Channel 2, a medium gain

Pre-EQ Overdrive channel. Cleaner sound is achieved at lower settings (3 to 5),at higher
settings (5 to 10) medium overdrive occurs which will produce more sustain and distortion.

[5] VOLUME: Controls the volume levelof Channel 2.
[6] BASS, MID & TREBLE: Classic passive tone controls thatregulate low, mid and high

frequencies respectively, of Channel 2.

In this Pre-EQ Overdrive channel thetone control circuit is located before the overdrive stage,
therefore it pre-shapes the overdrive tone which results in a bluesy type of distortion with lots
of sweet mid-range harmonics.

[7] GAIN: This GAIN knob controls the amount of distortion in Channel 3, a medium gain
Post-EQ Overdrive channel.
Cleaner sound is achieved at lower settings 3-4, at middle settings 4-6 medium overdrive
occurs which will produce more sustain and distortion. At high settings 6-10 heavy overdrive
occurs, adding a lots of sustainand compression.

[8] VOLUME: Controls the volume level of Channel 3.
[9] PRESENCE: Controls the amount ofboost in the upper mid frequency range of Channel 3.
[10] BASS, MID & TREBLE: Classic passive tone controls of Channel 3.

In this Post-EQ Overdrive channel the tone control circuit is located after the overdrive stage,
therefore it shapes the final overdrive tone which results in a more raw and rock type of
distortion with lots of grind anddynamics.

[11] GAIN: This channel has four gain stages and thereforedelivers lots of sustain and
compression without losing dynamics.
This GAIN knob controls the amountof distortion in Channel4. Cleaner sound is achieved at
lower settings 3-4, at middle settings 4-6 medium overdrive occurs which will produce more
sustain and distortion. At high settings6-10 heavy overdrive occurs.

[12] VOLUME: Controls the volume level of Channel 4.
