I started thinking about this, but when people say "it has a good neck", do they talk about quality, or feel??
Because I start to think many people talk about feel. Like, "this is a good neck, it's very thin and has a nice satin finish" or similar. That doesn't say anything about the quality. I see this often when people talk about guitars.
That's their opinion, and that's fine, but it has nothing to do with how good a neck is.
A good neck is basically a STABLE neck. You can add good fretwork and good finish to that, but both of those two factors are fixable in some ways. But a stable neck is way more important.
I have a friend who was super impressed with his Agile 9-string... I wasn't. It plays super nice (even tho I can't really play a 9-stringer to save my life, I just had it over to change his strings and do a setup) but if I'm not crazy, that neck was weak as hell. I remember setting it up a while ago, and just raising the saddles for a higher action made the neck bow a little so I had to fix the truss rod. Then I tested pulling the neck a bit forward and backwards, and I THINK I'm right, but it feels like it's of rubber or something. And it's a fucking 5 piece neck ,so I wouldn't expect that.
Another friend bought a brand new Gibson SG with a severly warped neck
What you think?
Well when people say good neck it's usually based on feel and such.
As for stable necks, yeah gibbons with warped necks aren't too uncommon. Most all my necks are super stable but I live in a pretty stable country weather wise. It's just usually warm and not too humid.
