Outstanding basses. But Yamaha BBs are a little like Musicman basses in that all the electronics are proprietary and there is a "Yamaha BB sound." To my ears it's very round in the high end and slightly modern. I love the way Yamahas sound and I'm glad they're becoming more popular again. I had a BB1600 in college - many gigs.One of these active 5-string PJ's happens to be at the top of my current GAS list.

If you are on a budget and you want something that looks and sounds a bit more traditional, a [Invalid or Expired Link Removed] is hard to beat. They use proprietary elex too, but they are trying to cop a hot rod Fender tone. You can buy an alder-bodied model for $599 brand new. Honestly I'm not sure I'd recommend a PJ anywhere up to the ~$1500 point over one of these.
If you can stretch to the $2000-$2500 point, I'd recommend a Invalid Link Removed or a build-to-spec by Nino Valenti, which you could do with your choice of finish, hardware, and electronics starting with his T21-P model.
Above that, Sadowsky NYC at about the $5000 point. I'm not sure but don't think they do a Metro in a P shape.
