I thought vintage spec Fender's had rounder a generally rounder neck radius than modern Fenders? I've also read from many other posters here and on other forums that neck radius has no affect whatsoever on action. I don't see how it could.
To the OP - I have the 2008 NAS P Bass, and have the action set up pretty low with little to no fret buzz. It isn't unreasonably low, but your action settings should only correspond to your technique anyway. Low action requires more time spent on technique than it does spending money on more expensive instruments. I'll bet if you played a Fender and a Sadowsky with the exact same action specs, you'd get similar fret rattle on both. It's all in the fingers, dude. If you think your Fenders have setup issues that are affecting playability, take them to a technician and have him (or her

) look it over, and throw a new brand of strings on while they're at it.
And then spend as much time over the next couple months playing acoustically (unplugged) as you do through your amp. Listen to how the wood, frets and strings on your basses react to your touch and you'll eventually learn how to avoid fret rattle with even the lowest action. Of course, whether it actually sounds good is another issue. Super low action isn't exactly a winning formula for having a fast array of dynamic capabilities.
Not to come off the wrong way but you're wrong.
A flatter fretboard radius does allow for lower action.
A Sadowsky will blow a Fender away!
Iv'e been doing my own setups and putting strings on not only
for myself, but for others too for 9yrs. I should have it down by now. I don't like SUPER LOW ACTION on my basses anyway. Im more of a medium/low kind of guy. When I do a setup for someone else, and they request a low action, I make
it as low as it will go without getting fret buzz. That means
no two basses are alike. Some have SUPER LOW ACTION, some don't. That's just the way it goes. To aquire a very low action without fret buzz you have to have perfect frets, and make the neck straight as an arrow.
I have had some stock basses fresh out of the box with
perfect frets and I achieved low-low actions on. Others didn't and the action was higher, so a fret leveling is the only way to remedy that. Sorry to say im not a good fretman so I won't mess with them, except for sharp edges. I also understand playing style and technique has much to do with it too.
For instance, im a fingerstyle player that is heavy handed,
I use 45-100's or 45-105's depending on the string, and play with a medium low action. If im doing a setup for a person who is a jazz player who has a light touch, likes to tap, slap, and pop, I'll use 40-95's or 45-100's depending on the string, and get the strings as low as possible. A metal player who plays with a pick, might get 55-110's and a medium/high action to avoid strings from flapping on the fretboard and also to provide good clean tone and sustain. With any bass, you
get better sustain with the action a little higher, especially a Fender. Hope this Helps.
