Ok, today I finally found a Music Man Bongo 5 string at my local music store.
After playing it for about 20 minutes I realized that the G-string does sit a little closer to the edge of the board than other basses I have owned... however, it wasn't a big deal. I was able to adjust to that just fine after a few minutes.
I fell in love with everything about the bass... it's a dark pewter sort of grey, and the string spacing is just perfect for me. The EQ is the most musical and powerful of any bass I've ever owned.
I went ahead and pulled the trigger and now am the owner of a beautiful, used 5-string Bongo!
Gonna try to get some pics and do a NBD thread soon. Seriously, I've gone through a LOT of basses and this is my absolute favorite yet.
Don't think I'll be getting rid of this anytime soon.
