Technical information

14 LEAD
Controls the amount of distortion in the LEAD mode; the GAIN (12) and LEAD controls
are used to define the relationship between the Crunch and Lead signals.
CAUTION:
Extremely high gain and volume levels in the Crunch and Lead mode can produce
strong feedback. Avoid feedback squeals, they lead to hearing loss and damaged speakers!
15 BASS ...........................................................................................................................
TIP 5
Bottom end voicing control for the Crunch/Lead channel.
16 MIDDLE ......................................................................................................................
TIP 5
Mid-range voicing control for the Crunch/Lead channel.
17 TREBLE .......................................................................................................................

Upper range voicing control for the Crunch/Lead channel.
18 ROUGH / SMOOTH ..................................................................................................
TIP 6
Switches between two completely unique overdrive characteristics in the Crunch/Lead channel:
ROUGH: emphasis on high and low ends.
SMOOTH: emphasis on midrange, suppresses the gritty upper frequencies.
19 REVERB
Reverb control, adjusts the portion of the reverb signal and increases reverb intensity in the Crunch/Lead
channel if you rotate it clockwise; the reverb can be switched on/off via a footswitch (jack 31).
20 CRUNCH VOL.
Volume control for the Crunch channel. (in front of the FX loop, affects the SEND level)
21 LEAD VOL.
Volume control for the Lead channel. (in front of the FX loop, affects the SEND level)
22 CRUNCH/LEAD
Channel switching between Crunch and Lead. Yellow LED illuminates when the Crunch channel
is active, the red LED indicates the Lead mode (both LED´s next to the respective Volume controls).
Use this pushbutton to pre-select Crunch or Lead. This function can also be activated via footswitch
(at jack 30) in this case the channel selector pushbutton is deactivated.
23 PRESENCE RATIO ......................................................................................................
TIP 7
This control defines the Treble response in the Crunch/Lead channel in relation
to the Clean-mode; therefore it only functions in the Crunch and Lead channel!
24 DEPTH BOOST
Boosts the bottom end in the poweramp and is assigned to the Crunch/Lead channel;
it is deactivated in the Clean channel.
25 MASTER
Master volume control for power amp output; the feature to switch between two Master volume
levels (Hi/Lo-Master Volume) can be accessed by means of a footswitch (See 31).
26 STAND BY
Poweramp standby switch. Use this feature during a break; the amp is ready ready to perform
at once, because there is no duration caused by the period to warm up the tubes. In order to
save energy, we recommend, to switch the amp off (27) during a longer pause.
27 POWER
AC power on/off
