Playing catch-up a bit, just found this thread. I've got a TB-10, bought from Wunjo about this time last year. (In case you didn't see the thread I posted at the time, it's the one used by John Giblin on Kate Bush's "Before The Dawn" gig).
Mine is used mostly for at-home practice, solo and with friends on acoustics. I can see it being used for acoustic jazz or country/americana gigs at some point, it's been tried in my electric jazz outfit but it didn't really fit.
The only gripes I've had is that the pre-amp rattles a bit in its cubby hole, but it's only really audible when you're playing acoustically.
I've used the end-pin for "upright" playing, but only when seated and positioning the bass like a cello. Standing, there's not enough body size to stop it rotating in place while playing.
