Aren't we all!
If had spent less time listening to the nonsensical fallacies about Gibson products and specifically Thunderbirds I would have saved tens of thousands of dollars on basses and been happier with my sound sooner.
When I first started playing, the pro advice from bass players I knew and general consensus from TalkBass was - start with a passive Jazz and add a PJ if needed. I did that, acquired a number Jazz basses trying to find one I liked, but just never felt good about the sound. Then went the PJ route and it got better but just never utilized the bridge pup much. Logically I dumped the PJ plan and went with a plain Precision and that more or less scratched the itch for a bit but I still wanted more balls and a broader range of tones.
Decided to take a side journey down the active humbucker path with Alembics, Spectors, Warwicks and Stingrays and that was an improvement but something else was still lacking. Then I bought a Gold Anniversary Tbird and BANG! That was it, the exact sound I was after all along. By this time I was probably 30 bass purchases into the journey.
Since then almost all subsequent purchases have been Tbirds in every sound flavor imaginable. I have active birds, passive birds, PJ birds, single coil birds, single humbucker birds, dual humbuckers birds, triple humbucker birds, split coil birds, piezeo bridge birds, parallel and series birds, ukulele birds, short scale birds, standard scale, long scale, extra long scale, four and five string birds, fretless birds, fretted birds, fanned fret birds, semi hollow body birds, set neck, neck thru and bolt on birds. Maple, ash, poplar and mahogany body birds. Maple, mahogany, walnut, pao Ferro, and Wenge neck birds. And rosewood, ebony, maple, macassar ebony, wenge and blackteck fretboard birds. Pickups from Bartolini, Nordstrand, ChinaBuckers, Gibson Reissues, Epiphone 760ProBuckers, Dingwall, EMG, Greco, Sammick, Shadow piezeo, Burny pickups, TB+ pickups, and even Fender pickups. Along the Tbird journey I'm finding some body shapes and woods as well as neck shapes and woods and fretboard woods I like best, along with pickup types and placements I like best and control and layout designs that work best for me.
Someday soon I'll take all that knowledge and experience and build about four basses that I would consider Perfect Tbirds for me. A studio model, a stage model, a fretless and an active.
