TIP´s from the Designer:
To help you get acquainted with the amp's fundamental sounds, I recommend that you set all tone
controls to the center or 12 o'clock position. For higher Gain Crunch sounds, your best bet is to turn the
respective Treble knob well down to prevent the pickups and speakers from interacting at hi levels and
generating feedback (the recommended setting is somewhere in the 9 to 1 o'clock range).
The Clean and Crunch channels are equipped with dedicated Treble knobs. This means that you can
tweak the top end of each of the two channels separately to suit your taste and the given sonic
scenario. You will find that grittier tones generally sound better with a touch less treble because preamp
saturation makes higher frequencies figure more prominently in the signal.
9 Clean Volume
Volume control for the Clean channel (pre-FX loop, influences the Send level). The green LED beside this
control indicates Clean operating mode.
10 Crunch Volume
Volume control for the Crunch channel (pre-FX loop, influences the Send level). The yellow LED beside
this control indicates Crunch operating mode.
11 POWER TUBE MONITOR V1
This LED lights up when the current sent through the V1 power amp tube was too high and the power
tube monitor system has switched that tube off.
12 POWER TUBE MONITOR V2
This LED lights up when the current sent through the V2 power amp tube was too high and the power
tube monitor system has switched that tube off.
13 POWER TUBE MONITOR V3
This LED lights up when the current sent through the V3 power amp tube was too high and the power
tube monitor system has switched that tube off.
14 POWER TUBE MONITOR V4
This LED lights up when the current sent through the V4 power amp tube was too high and the power
tube monitor system has switched that tube off.
A few words on the POWER TUBE MONITOR system:
The electronic power amp monitoring system constantly gauges the current sent to the two power amp
tubes. If it rises to too high a level, the system shuts down the given tube.
This can occur when the amp is operated incorrectly (for example, if the impedance is wrong due to an
incorrect speaker load), at extreme power spikes, or when a tube is defective.
Reset this electronic monitoring system by switching the standby switch off and on again. When you
press the standby switch to turn the amp on again, the system again measures the current sent to the
tube. If it is still too high, the power amp must be checked by a service technician, and the tube may
have to be replaced if it is defective.
15 Presence
This control shapes the hi frequency response in the power amp stage and affects all channels.
16. Depth Punch
This control shapes the lo frequency response in the power amp stage and affects all channels.
17 Ch II Gain
This knob determines input sensitivity of Main Channel II (Lo & Hi Lead) and
it determines the amount of preamp saturation in both Lead channels.
CAUTION: Extremely high gain and volume levels in Lead mode can produce strong feedback. Avoid
feedback squeals, they lead to hearing loss and damaged speakers! Reduce the Gain, Treble and
Presence levels at higher volumes in order to avoid uncontrolled feedback!
18 Lo Lead Bottom
Alters the EQ by boosting the low end range; this Bottom feature affects the Lo Lead mode.
19 Hi Lead Bottom
Alters the EQ by boosting the low end range; this Bottom feature affects the Hi Lead mode.
A tip from the designer:
If you really want to beef up the low end of your lead tone to dial in the type of sound often employed
in contemporary styles, press the Bottom button. Note that you can activate this feature separately for
each of the two Lead channels.
