Mod Piledriver Troubleshooting Supplement

Use this troubleshooting supplement to help:

Measure DC voltage test points to identify major discrepancies and locate problem areas.
(Keep in mind that the voltage measurements will vary slightly from kit to kit. The voltages you measure should be in
the same ballpark, but do not expect to get the exact same value.)
Using a volt meter, connect the ground side lead of the meter to any ground point on the pedal.
One ground point would be the output jack's ground lug. The other volt meter lead will be used to
measure DC voltage at the test points shown below.
Guitar cable must be
plugged into the input
jack while taking voltage
measurements
INPUT JACK
First, plug a guitar cable into the input jack and take measurements at each test point with the
control turned all the way down (min gain) taking note of each measurement. Next, take
measurements at each test point with the control turned all the way up (max gain) and take note of
each measurement. Any major differences between the voltages listed above should indicate a
problem area.
Measured at Minimum Gain
