Hello,
I'd like to have some details to try to make it
Can you Confirm :
1) Bridge 500k --> cap 47nf
2) inner coils series 500k --> cap 47 nf
3) Neck Bridge Parallel 250k --> Neck AND Bridge in Parallel should be 500K cap 47nf
4) Inner coils parallel 250k --> cap 22nf
5) Neck 500k --> cap 47nf
Nota for positions 2 and 4, one of the two humbuckers have to be reversed (turn 180°). If not these positions will be not hum cancelling.
Regards
Mentor
