I even do it playing my headless Factorbird fretless which has zero neck-dive.

(no headstock, heavy solid Koa body) Aside from aiding neck-dive (at whatever level) on a standard T-bird, overlapping the jutting lower bout with your strap draws the guitar body to your body and stabilizes it so focused playing isn't being compromised/distracted by fighting the instruments ergonomics. Many T-bird players ride their basses lower which works for them, but playing one in a less R&R position benefits from this simple functional solution. I am well aware that playing a T-bird is all about how badass they look and sound, (and I 100% agree with that) so my addressing that particular design shortfall is only to offer advice to help make playing one more comfortable/enjoyable. Not slagging T-birds, why would I as a "dyed in the wool" T-bird player since 1974 when it was my only instrument? I would have to say I am one of the T-birds' greatest advocate, and as a designer/builder of basses I am keenly aware of how to make an instrument that makes playing it effortless. Most production basses have design compromises - as proof there is no
one design that everyone uses. Add to that the very active "modding" community which reinforces players making their chosen basses uniquely their own.
