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

S

ocket 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. Bright

High   frequency   boost   for   the   clean 

channel.

5. 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.

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.
