This is not a newbie question. Or maybe it is, from someone who's been around for a while but never experienced this before. I've been doing my own setups for decades, without a problem, so please read carefully before responding. My Bongo is weirding out on me. I don't use it a whole lot lately, decided to take it to a rehearsal last week. Noticed the action had gotten pretty high, there was a little play in the neck, I tightened it up a bit... and the action was still higher than my preference. Sighted the neck, and it's pretty much straight now (little if any relief), and the bridge saddles are all flat against the plate. The action was pretty sweet on this bass when I got it, and I've no clue what's going on. Do I have to shim it? If so, what's the best way as I only shimmed one other bass since I've been playing. And it was a POS that I didn't care much about. This here is one of my babies. Also, what could cause this to happen? I'm kinda stumped.
