I am always surprised how neck radius make such a big difference for some players in that I barely notice the difference at all. Can you guys feel the difference or is it more about set up?
Yes, over time I've developed a clear preference for flatter fretboards on basses and guitars. On four-string basses and guitars, I like at least 12", but some of mine are 9.5", and provided I like the neck otherwise, that's fine. For example, I love the necks on my 2003 Jazz and 2004 Strat, which have 9.5" radius fretboards. But I do prefer the 12" radius fretboards on my SB-2 and JB over my Fender J's.
On five-string basses, I want at least 12", as on my M-2500, and I'd happily go much flatter. For me, this provides less of a "hump" to reach over to access the lower strings, and helps playability in general. Last year I bought a used JB-5 with the standard 9.5" radius, and the neck is shaped so wonderfully otherwise that I enjoy playing it--but it just makes me think how much
more I'd enjoy it with the 12" radius. I'll probably sell it for this reason.
Backstory: When I resumed playing in 2002, I knew nothing about bass specs, and just played my old Peavey from 1988. After a couple of years, my herd stabilized at my 2003 Jazz, a 2004 MIA Precision, and a DiPinto Belvedere semi-hollow. I loved the Fenders, but noticed I could get lower action on the DiPinto, and play a little better on the DiPinto when sitting (i.e., when the long reach to first position when standing wasn't a factor). I loved the feel of that neck. Eventually I asked Chris DiPinto about the radius, and it was 14".
This was my first clue that radius was a factor, and it was confirmed when I got #8 necks on an L-1500 and my SB-2 in 2006 and 2007 (1.5" nut, 12" radius). Even then, the Fender necks felt more natural at first grab, but I soon realized I could play more easily on the G&L basses, just like the DiPinto. I've strayed a couple of times, as with the JB-5, but those instances have just confirmed my preference. When testing basses in shops, I've also noticed I prefer the flatter fretboards, like those on Yamaha fives.
My experience, though, is that even if I am not used to a particular kind of instrument, if I play it enough, the nut and radius will eventually not be a problem. I adjust, sort of automatically. It's not a skill. It just happens. It's like my body eventually wraps around that particular bass.
I see that this may not be an option for people who have physical difficulties like tendonitis and so forth. I can clearly understand why.
You know, this is what happens with me. I respect the fact that it may not happen for everybody and it's fine. Bodies are different. And while we all adapt (it's a human trait), we can adapt to some things that others can't and the reverse is also true.
This is largely my experience too. I can get comfortable on many basses (and guitars), but then when I go back to one the fits my preferences, I think "ahhhh....much better." For example, I adapted well to my 2008 Fender Jazz V and played it regularly, but whenever I moved over to my M-2500, I felt much better. The Fender didn't last long after the M showed up.
Some of this is because I've had hand and finger issues over the years. I want my instruments to be as easy to play as possible, which, for me, means wide nut widths, vintage curvy fretboards, and wide string spacing (on fives) are out of the question. Undoubtedly, it's the opposite for others.
