1. Channel selection
Switch to change channels of the
amplifier. It works only when Jack is
unplugged from the Footswitch socket.
In position “up” the clean channel is
on, whereas, in position “down” the
distorted channel is on.
2. Footswitch
Socket to
connect a
footswitch, with
controlled
Channel
switching and
Gain selecting.
TRS Jack socket
(T – tip:1, R – ring: 2, S – sleeve: 3),
where tip changes channels, ring -
changes masters, sleeve is ground.
It
uses “stereo” cable, which can be also
replaced by “mono” cable, however
then, the Gain switch will not be active
and, in the amplifier, only
potentiometer
Gain 2
will be active.
3. Input
Input jack socket to connect to the
guitar.
4. Clean Volume
Volume of the clean channel.
HINT: At a low setting of this
potentiometer, you get a clean sound.
When you boost the clean
potentiometer, you get sound that is
more saturated until some crunch is
achieved. When you turn the Master
down and boost the Clean , you obtain
more crunch. So you can get crunch on
both channels, which, at the same
time, differ in character and dynamics.
5. Bright
High frequency boost for the clean
channel.
6. Gain 1
Gain control for the distorted channel.
HINT: With a little value you can
obtain crunch effect or overdrive. By
adding gain, distortion is added until
reading high gain. For guitars with
Humbucker pick-ups and high output
signal, it is possible, that turning the
knob to the right, does not cause more
distortion.
It only gives more noise of
the amplifier. It is designed that way,
because each guitar has a different
output signal level, and the value of
gain was set up that way, that in the
case of guitars with less signal, it is
also possible to get more distortion.
7. Gain 2
Second gain control for the distorted
channel which is only available when
the footswitch is used.
This is a duplicate of Gain 1 . They
both can be set independently and
selected with the use of a footswitch.
HINT: This potentiometer can be used
to boost distortion, e.g. while soloing.
To achieve such effect, set
Gain 2 knob
in such a way that after switching from
Gain 1 , the more distortion is heard.
8. Drive Volume
Distorted channel volume. Proportions
between clean and distorted channel
can be set by this potentiometer.
9. Bright
High frequency boost for distorted
channel. Apart from high frequency
boost, the switch also changes
distortion character. It is possible that
using certain controls of equalizer or
gain, high frequency boost will be less
noticeable.
