From a ToneQuest Magazine article that had a Joe article and a review of the Gigliotti's they were in their infancy at the time.
The bridge design is string-through-body, just as it should be
(hate those top-loaders), with six fully adjustable, non-vintage
saddles. The pickups in our Gigliotti are the same used
for the first Tele given to Joe Bonamassa — a Seymour
Duncan Vintage ‘54 bridge and Alnico II Pro neck. The
inherent Tele brightness is nicely tempered by the mahogany,
and we liked what we heard from the bridge. However, the
neck pickup left us less than enthusiastic. Don’t fault
Seymour — he has re-created a softer, more musical rendition
of the the original neck pickup sound of the early
Telecaster, but we still found it to be a little muddy, dull and
uninspiring. What do you do with it? How about losing it
altogether. We’d like to see a Gigliotti Esquire, or at least
another take on a neck pickup with some attitude from
Duncan, Harmonic Design or Lollar, perhaps. Or how about a
set of Bardens? They are not a ‘traditional’ Tele sound, but
they will pin your ears back with some mighty big tone.
Since Gigliottis are all custom-built, you can pick your poison
when it comes to pickups. How nice is that!
Joe usually played his using the bridge pickup because he thought the same about the neck. I think that is why they changed but this was the original PU set up.
