1. Input Jack. This ¼'' jack accepts the output from the guitar. 

2. GAIN control of equal Channel I and Channel II control panels. This control 
adjusts the amount of drive for Channel I (Channel II). Higher settings of this 
control increase additional harmonics and sustain. 

3.  BASS,  MID,  and  TREBLE  controls.  These  controls  represent  an 
equalization section of Channel I or Channel II.  

4. VOLUME control. Adjusts the overal volume of the Channel. 

5.  CHANNEL  SELECT  switch.  Each  Channel  section  has  its  own  channel 
select switch to select one of the four channels as desired. 

6. BRIGHT switch. Three-position high-end boost (center = off, left = bright, 
right = brighter). 

7. 

Channel ON indicator. Each channel has its own “on” indicator which lights 

when the channel is selected. Channel I 

– green, Channel II – blue, Channel 

III 

– yellow, Channel IV – red. 

8.  GAIN  control  of  equal  Channel  III  and  Channel  IV  control  panels.  This 
control  adjusts  the  amount  of  drive  for  Channel  III  (Channel  IV).  Higher 
settings of this control increase distortion and sustain. 

9.  BASS,  MID  and  TREBLE  controls.  These  controls  represent  an 
equalization section of Channel III or Channel IV.  

10.  PRESENCE  and  ANGLE  controls.  These  controls  add  yet  another 
dimension  to  powerful  equalization  groups  of  controls.  Channel  IV  has 
ANGLE  control  which  was  intended  as  custom  option.  Here  it  works  as 
PRESENCE like on Channel III. 

11. VOLUME control. Adjusts the overal volume of the Channel.
