so the JD wiring,
starting at the bridge pickup, position 1.
Position 2 gives the out of phase strat 'inbetween' sound
Postion 3 both pickups in parallel (like a normal tele)
Position 4 is the neck pickup plus some sort of capacitor which tries to make the neck pickup sound like a humbucker (roll the tone down a bit and it's not toobad)
Position 5 is the neck pickup.
I actually have 4 vintage guitars now, one is the Geoff Whitehorn signature from July 08. I keep this in my office and use it to learn songs on, during lunchtimes.
I have an SG with vibrola and a 335 type, both used in my Paul Weller and Stereophonics tribute bands.
They are all excellent guitars and hold their own against my other higher range stuff. (I have 3 Les Pauls, an SG jr, PRS signature form 1989)
I am making it my goal to only gig with these cheaper instruments as taking 3 to 4 grands worth of guitars is starting to bother me
