I'm looking to commission a fully carved Upton so I am offering my hybrid Brescian.
If you were at the ISB this bass was there. If not, I can tell you it's everything they say it is.
Jazz cannon and pipe organ like arco for section work.
If I sell locally, I won't have to worry about shipping back to Upton for a trade in so if you're closer to Columbus, OH than the east coast and you want to play before you buy, here it is.
Only thing I've changed is the end pin. Changed to carbon fiber.
There's a good pic on Upton's blog... http://blog.uptonbass.com/
Let me know if questions.
