So the Bartolini preamp is toast on my Yamaha BB605. What to do? I like this bass...enough to keep it over some other big name, quasi-boutique basses. The bass isn't worth much working preamp or not. Maybe $300. So, do I... 1. Get a new preamp - like a U-Retro with active/passive option and passive tone control - even though the preamp will be worth more than the bass. 2. Wire it passive and use an outboard device - Sadowsky, Aguilar, East, Avalon U5, etc. 3. Look for a new 34" scale 5 string bass that I will like as much as this one - I haven't had much luck with this which is why it's listed last. I know what I think. Curious what any of you think?
