this is the problem:
my circuit produces a crack sound on every string but more hearing the low frequencies of wound strings
in the circuit there are 2 di marzios (the tone zone, super distortion) each wired to on on on miniswitch (parallel, tap, series) ----------------> to 3way switch (for pick ups selecting) --------->to 500k linear pot
for the ground i had bypassed the 3 way switch and wired directly to 2 miniswitch, iis it the problem?
or the noise can be produced by bad soldering?
