My Mom's 1979 has T-Tops. They are nice pickups, not enough gain though....Okay, so you are not trying to ape Page's tone, you just want the phasing options like he had in #2? Cos most of his tone was from #1, which didn't have the switching - that unique sound was a PAF neck and T-Top bridge (from '72 on) played in the middle position, not from phase switching.
A colleague just paid quite a good deal ($750.00) for a pair of T-Tops from a well know (here anyways) collector.
