Matt - I've been considering for some time now having my R&B Custom bass neck narrowed. It's not too fat, but just a bit wide... if it was shaved a bit it would make the 36" scale neck feel a bit shorter is my thinking... After that, I would pull the monorail bridges, and, after reading Rod's review, I'd replace the 'rails and install a Babicz bridge. My only problem with the bridge though would be with my current pickups - they're Areo's, and custom made for the odd string spacing this bass has, which is (from B-to-G) 19/18/18/17mm... so I'd have put in new pickups. The plus side of putting on the Babicz though, is I would have a much wider and available pickup selection to choose from.
Now for the spoiler... Babicz only comes with a 19mm spacing. So narrowing my neck wouldn't let me use it, so that's out. I'd have to search for either a narrower bridge, or an adjustable side-to-side model. Any suggestions?
You can see from this picture of my bass the uneven string spacing.. not a bad thing per se, but has anyone ever seen or played spacing like this before?
