I don't know if this mod has been covered before, if it has...delete this
I've had a few Kinman Blueprint strats (which are very nice axes),
and Chris Kinman had a different wiring system on his strats...
He had the bottom tone pot wired as a neck pickup volume, so whatever
pickup was selected, you could wind in the neck pickup as well.
This gave all possible pickup combinations (well, the two you
can't normally get..bridge and neck..and all 3 together)
Sorry I haven't got a diagram...Chris Kinman doesn't make guitars
anymore, only pickups...shouldn't be too hard to work out though...
There may have been a diagram in an old Sonics mag...if I can find it, I'll post it
It's just a way of making a seemingly stock Stratocaster more versatile
Cheers
