I've owned a few of the TRB basses. A TRB6, a JP1 and a TRB1006J. The TRB6 and the JP were both very old and Japanese built, they were a totally different level to the TRB1006, both being completely luthier built. The TRB1006J was though a very, very nice instrument, a lot better than the price would lead you to expect. A friend of mine who's a very, very fine solo bassist plays one, and loves it.
