Title: Dual HB Inner coils series / parallel with 5-way switch, dual vol
Post by: david.lightman on February 06, 2021, 07:48:06 PM
Is it possible to wire dual humbuckers with 500k & 250k volume pots on a 5-way switch to have:

1) Bridge 500k
2) inner coils series 500k
3) Neck Bridge Parallel 250k
4) Inner coils parallel 250k
5) Neck 500k

No tone pot (don't judge me).  I've done quite a bit of searching on the interwebs and haven't quite found my answer.

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.

Note :
Neck humbucker is reversed
Coils not indicated 1 (on) are off (0)
Example : pos II Bridge south coil is off and Neck north coil is off too
