Yamaha TRB-1006 (sold)
This 35’’ scale 6-string bass has been upgraded with Kent
Armstrong preamp circuitry, which allows for a wider and
more subtle range of sounds than the original electronics were
able to provide, as well as boosting the overall warmth and quality
of the output.
Also, the plastic nut has been replaced with a brass one which helps
the sustain, and the stock plastic knobs have been upgraded (!?) to
metal ones, thus allowing for a more dynamic "twiddling" experience.
Despite having a decent sound, I'm not a huge fan of Yamaha's
wide 6-string necks - despite having hands the size of snowshoes.
Also, it weighs
about the same as an pregnant elephant about to give birth to triplets.
