●True Bypass Switching lets your instrument's signal pass through a non-
 electronic bypass line when the effect is disengaged, feeding your amp with 
 direct, unaltered signal from your instrument.  
 Low noise mechanical switch is used for effect/normal switching.
●LED to indicate effect/bypass and battery condition for trouble-free
 performance.
⑤LEVEL
This controls output level of 
effected signal.   Typically output 
levels of both normal signal and 
effected signal should be adjusted 
to equal levels.
⑥FOOTSWITCH

⑧DC IN (power input jack)
A jack for connection of external 
power supply to effect.   Be sure to 
use the correct Maxon AC 
adaptor. 
  Turn down amplifier's volume 
  to the minimum before 
connecting AC adaptor to the 
product in order not to damage 
other connected equipment.

TONE
This controls the amount of high 
frequencies.   Turn it clockwise for 
more treble and counterclockwise

⑦LED INDICATOR
This indicates the effect/bypass 
status and battery condition. It 
lights when plug is inserted to 
input jack and effect is on. No LED 
light indicates the battery is low or 
not installed.   In this case replace 
the battery.
