a.  DELAY (OFF or ON):  Turns the delay OFF or ON.  Controlled by 

the  VALUE  knob  or  the  DELAY  switch.    Turning  the  Delay  OFF 
mutes both the input and output of the delay, so the delayed output 
stops immediately. 

b.  DELAY  LEVEL  (OFF  to  0  dB):    Controls  the  level  of  the  delayed 

signal. 

c.  REGEN  LEVEL  (OFF  to  0  dB):    Controls  the  level  of  successive 

repeats of the delay, and therefore the number of repeats that can 
be heard.  If set to 

–10 dB, each echo will be 10 dB lower than the 

one before it. 

d.  DELAY  TIME  (10  ms  to  1300  ms):    1300  ms  =  1.3  seconds.   The 

delay time can also be set by pressing the 2

nd

 switch, then pressing 

twice  (tapping)  on  the  DELAY  switch.    The  time  interval  between 
taps will set the delay time.  You can tap twice again to change the 
setting.    If  the  interval  between  taps  exceeds  1300  ms,  the  delay 
time  will  be  set  to  1300ms.    If  you  only  tap  once,  after  a  few 
seconds the time will be set to 1300 ms.  Press 2

nd

 again to exit the 

tap function. 

e.  DELAY PAN (0 to 100):  Pans the delay output.  0 is fully Left, 100 

is fully Right, and 50 is centered. 

 
 

K)  REVERB Function 

 

a.  REVERB  (OFF  or  ON):  Turns  the  reverb  OFF  or  ON.   Controlled 

by  the  VALUE  knob  or  the  REVERB  switch.    Turning  the  Reverb 
OFF mutes only the input to the reverb, so the reverberated output 
‘spills over’, even if set to OFF in the next preset. 

b.  REVERB  DECAY  (0  to  99):    Sets  the  relative  decay  time  of  the 

reverb. 

c.  REVERB HFDAMP (0 to 99):  Set at 0, the highs will decay at the 

same  rate  as  the  lower  frequencies.    At  larger  settings,  the  highs 
will  decay  more  rapidly  than  the  lows,  so  the  room  will  sound 
‘darker’.  A setting of around 20 will sound more natural, since real 
rooms always absorb high frequencies faster than lows. 

d.  ROOM  SIZE  (SMALL,  MEDIUM,  or  LARGE):    With  other  settings 

being  equal,  a  larger  room  will  have  a  longer  decay  time,  since  it 
will  take  more  time  for  the  sound  to  travel  from  one  surface  to 
another. 

 

L)  SWITCH Function 

 

a.  P/T SWITCH: (PHASER, TREMOLO, or PHA+TREM):  Determines 

the  action  of  the  PHASER/TREMOLO  switch  and  LED.    Set  to 
PHASER,  the  switch  will  turn  off  or  on  the  phaser,  or  if  2

nd

  is 

activated,  the  switch  will  allow  tap  setting  of  the  phaser  rate.   The 
LED  will  show  the  phaser  is  on  by  blinking  at  the  set  rate.    If  this
