GROUND
Guitar cable must be
plugged into the input
jack while taking voltage
measurements
Connect your guitar to the input jack and take AC voltage measurements at each test point with
both controls turned all the way up. At each test point the AC voltage should increase dramatically
each time you strum the guitar. (No strum = 0.0 VAC, Hard strum = anywhere from 10 mV to 2 V).
