I'm having some difficulty debugging a BYOC/EA Tremolo build. It was constructed per the layout on this site with no part substitutions. When the pedal is engaged, the LED priefly pulses, then stays dimly lit. The signal is distorted with no tremolo. The volume knob adds lots of output, but the Rate and Depth controls don't seem to change anything other than the character of the distortion. Here are my voltages (taken with pedal engaged, all knobs fully clockwise):
Q1: D 9.33
S 5.27
G 3.14
Q2: C .28
B .81
E .24
Q3: D 0
S 0
G briefly about 3v when pedal is engaged, then rapidly falls to 0
Q4: C 2.7
B .58
E 0
Any ideas????
