7 Reverb:
Reverb intensity knob. Twist it to adjust the amount of reverb for Clean and Lead. Turn the
Reverb control knob clockwise to increase the effect's intensity. The signal remains completely dry
when the knob is set to the 7 o'clock position or if Reverb is deactivated via a footswitch. You can
switch the reverb unit on and off using a footswitch connected to jack 18. The reverb unit is always
on if you do not plug a footswitch into jack 18.
8 Lead Volume:
Volume control for the Lead channel (pre-FX loop, influences the Send level).
The red LED above the channel switching selector (11) indicates Lead operating mode.
Use this knob to dial in the desired balance of levels between the Lead and Clean channels.
9 Mid Boost:
This voicing feature operates globally, affecting both channels by boosting specific
midrange frequencies when activated. The LED above the button lights up to indicate Mid Boost
is activated. It may also be switched using a footswitch connected to jack 19.
When a footswitch is plugged in, the front panel Mid Boost button is disabled.
A tip from the designer:
Mid Boost targets and shapes specific midrange bands crucial in voicing a guitar's sound.
This tone-shaping option is remotely controllable via footswitch, so you can adapt the amp's
fundamental sound on the fly, say to better support rhythm guitar work, singing leads,
and slashing power chords.
10 Gain Boost:
Press this button to increase the Clean and Lead channels' amplitude. The red LED
above the button lights up to indicate Gain Boost is engaged. You can also control Gain Boost
remotely via a footswitch connected to port 20.
A tip from the designer:
Engaging Gain Boost in the Clean channel slightly increases the gain level and subtly changes the
frequency response. This brings out the middle frequencies and conjures a more assertive tone for
throaty riffs and gritty lead lines. Activating Gain Boost in the Lead channel kicks up the gain level
considerably, saturating the preamp to give you more sustain for playing leads.
11 Clean/Lead:
Channel selector pushbutton for Clean and Lead modes, red LED indicate Lead mode;
This function can also be activated via the respective footswitch connected to jack 20.
Once a footpedal is connected, the channel selector pushbutton is deactivated.
12 Master:
This master volume knob controls the power amp's output (it is located post FX Loop).
M.V.B. (Master Volume Boost)
: This feature increases the master volume level, giving you instant
access to two different volume levels for different musical situations, for instance, one for rhythm
parts and the other for lead lines.
You can control this feature via a footswitch connected to port 19.
13 Power Tube Fuse:
This red LED lights up to indicate one of the internal power tube fuses has
blown. You can continue playing, but the amp's performance will be diminished. Normally the
loss of a power tube results in an unbalanced signal.
Be sure to have a specialist look over the power amp as soon as possible; the fuse probably blew
because of a defective power tube. Once a fuse has blown, it must be replaced by a new fuse.
14 Stand By:
Power amp standby switch: Use this switch to silence (0 position) the amp when you
take a break. The amp's tubes stay warm, which means that it is ready to roll immediately
when you switch it back to full power. The standby switch is also well-suited for muting the amp
for brief breaks, for instance when you're switching guitars.
A tip from the designer:
I suggest you get into the habit of using standby during short breaks. In this mode, current is not
piped through the power tubes, so they don't get as hot (due to the lack of anode dissipation) and
are spared considerable wear. The amp is ready to run when you flip the Standby switch because
the tubes are already warm and don't require time to heat up. For breaks of 30 minutes and
longer, I recommend that you switch the amp off in order to conserve energy.
15 Power:
AC power on/off.
Please note: ensure that the Stand By switch (14) is set to Stand By (0 position) before you switch
the amp on. Let the tubes heat up for about 30 seconds before you activate the power amp. This
procedure spares the tubes.
CAUTION:
After an extended period of operation and higher ambient temperatures the amps's
chassis can become very hot, therefore avoid touching the rear panel surface !
