Hi gang,
I got an old Yamaha bass with SD P-bass pickups that has a little switch bank with 2 dipswitches. Can anyone tell me what are these for? Thanks.

switch 1 shifts the coil resonance, the resonance moves downward from 22 KHz to 6.4 KHz

switch 2 gives a broad band bass boost of 4 dB.

Thanks for the info.
So, is the quot;openquot; state of the switches the quot;offquot; position?
