I am not chasing them. They come with the guitar so I’m just wondering if They are ok or I need to budget a pickup set and the pain of changing the pickups in a semi hollow into the price
Depends if the repro is accurate: Burstbuckers were meant to be P.A.F. copies but were finally made of different materials and don't sound like the real thing (Gibson did even use died poly wire to make believe it was plain enamel, apparently... at least it shouldn't be an issue with T-Top clones since the real ones hosted poly wire by design).
Depends also on which T-Tops were modeled: between early ones with patent stickers and the last ones with engraved baseplates, there's sometimes noticeable differences (denying the supposed consistency of T-Tops: some of the late ones have an obviously higher DCR than 7.5k and those are NOT the best sounding).
Depends finally on the rest of the circuit... Gibson mounted 300k and even 100k pots in the late 70's/ early 80's: having such controls is like playing with a tone pot permanently rolled off on a guitar with 500k's...
Now, all the T-Tops that I've lab tested (with their stock short thin mags and not dulled by low resistance pots) had in common a high Q factor, giving a sharp focused brightness that I've not met in
any other humbucker.
Seems they were good enough for early Schenker, early Angus Young, late Jimmy Page, Randy Rhoads, BB King... Non limitative list.
One of my favourite neck PU's of all times is a patent sticker T-Top.
The LP Custom that I played in the early 80's had stock T-Tops and I had no troubles to obtain good sounds from it. It just needed a lil' help from a Boss OD. But it was certainly not worse to my young ears than the hot DiMarzio's previously mounted in my first LP copy...
Last but not least: when I worked on guitars with stock T-Tops, I've changed sometimes the 300k tone controls in no-load pots. It helps to awake the pickups (especially if they haves still their stock covers), revealing their bite and harmonic richness.
FWIW. YMMV.
