Start here: http://web.archive.org/web/20150609032908/http://wholelottaled.webs.com:80/ That's the archived version of the website that grew out of the links (now dead) in the very first posts of this thread. It moved home a few times, and eventually disappeared, but thanks to The Wayback Machine, it's still accessible. It's better, and more accurate, than just about any other Page gear site on the web. Lol - yes, that's pretty random! I doubt that anyone knows. Page is unlikely to remember, and his techs have changed over the years, so there isn't anyone (or at least, no-one I'm aware of) who has had continuous involvement with the guitar adn who would know something like that. You could always blow up those close-up photos and check for nibs. I'd do it myself, but I'm visually impaired... The JPP signature models from 2003 were very accurate by all accounts. The ones from the 1990's not really. Again, read that link. Neither had them whilst Zep were active. #2 had all the bells & whistles (series/parallel, coil splits, phase) added in the early 1980's. From that experiment Page decided that the phase switch was all that he really used, and eventually added a single phase switch to #1. Read the link Briefly, #1 had stock PAFs when Page got hold of it. he removed the cover from the bridge pup, revealing a double-white. That pup died in 1972, in Australia. After a brief rewind got him home it was replaced with a new Gibson T-top. That had a nickle cover to begin with, but that was removed post-Zep, revealing double black bobbins. Eventually that was replaced by a custom pup from Seymour Duncan. Neck pickup was stock PAF for years, & is now believed to be a 1960 PAF, as DADGAD says. By reports, #2 is louder & more aggresive. Plus the neck profile, whilst based on #1, is not so extremely slim. Many people prefer the #2 signature models for that reason.
