+9V 

 

Solder the input/output jacks (J1, J2), the 3PDT True Bypass footswitch (SW5), and 
the 9V battery clip. 
 
Note:

 

The big components tent to tilt when soldered. Make sure they are straight: A 

good idea is to solder only one pin and once you  are sure that it is perpendicular, 
solder the rest of the pins.

STEP 4 – Testing the Power Supply. 

At this point, the power supply of the circuit could be checked. Place a mono guitar 

cable at the input jack, a 9V battery and make sure that the footswitch is activating 
the pedal. The led should light and the following voltages read:
