Hi.
I also have the T-24, so my observations may, or may not apply on the 5er.
I bought mine with defective TR (stripped nut), so I didn't play it that much, and it's still under construction

.
The double acting TR on mine is (was) a nice feature, but as it's a "a nut in a barrell" style, the allen slot is tiny and will probably be stripped sooner than later.
The bass is tiny, and by tiny I mean funny looking on a heavily built (100kg/175cm) player. That may or may not pose a problem.
For some reason the pickups din't work well with my tube rig (thin as well) but on my SWR the sound was good.
The build construction and finishing is good, and for a NT, the price is very tempting.
IMHO "try before You buy" applies with this bass a bit more than usually.
Regards
Sam
