Re: Gibson Les Paul Question - series/parallel
There was a list floating around online of the 21 sounds (what push-pull combinations there were, but no suggested uses), I think it was a copy of something Gibson had printed with Jimmy Page's signature LP. I saw the list and printed it off years ago, and I believe there may be one or two more sounds that aren't included in the 21. As far as I know, the 1990's Jimmy Page LP was the first guitar by a major manufacturer to offer it, but that wiring could have been developed by someone a long time before that. Jimmy Page didn't have that wiring on his LP's during his Zeppelin years. If I remember correctly (and I may not), Gibson introduced the 500T/496R pair on that guitar, saying they were the hottest PU's they had introduced so far. Page wasn't happy about the way it sounded and stopped production. The signature guitar was later revived with more appropriate PU's, not sure what kind of PAF's.
Here is a list that I have been looking at.
02 R dn == dn up neck screw coil
03 R dn == up up neck slug coil
04* T dn dn == dn bridge humbucker
05* T dn up == dn bridge dual (parallel)
06 T dn up == up bridge screw coil
07* M dn dn dn dn bridge and neck humbuckers parallel
08* M dn up dn dn bridge dual and neck humbucker parallel
09 M dn dn dn up bridge humbucker and neck screw coil parallel
