weird low rider issue

[raph36]

hi guys!
just finished my lowrider (not the newest one, the 2014 one)
i seem to have a problem, but i'm not sure, everything works more or less, i have all octaves doing something, but one note out of two it doesn't really work, i only get weird noise (like an lfo), also at the end of each not i get this noise so , it starts right but end up with this noise as soon as the note start to fade, anybody knows where it might come from ? i have already tried to replace all the ics, still the same

thanks !

Tracking issue, what guitar/pickup configuration? I've found that hum bickers work better than single coils unless you put a slight boost in front.
