Or at least... what would you compare it to? This is a weird and random question, I suppose, since I own one and play it constantly, but I don't know the first thing about necks (D shaped? U shaped? no clue). What's weird is that I have a MIM Jazz with a skinny little neck that makes my hand cramp up every time i play down by the nut; the Peavey feels much more substantial than the Jaz. And I've got an SX P-bass with a fat baseball bat of a neck that feels alright in my hand, but is thick enough that it noticeably slows down my hand; in this case the Peavey feels much thinner and faster. After much playing of many basses, the T-40 neck seems to fit my hand better than any other. So if I'm right in assuming the T-40 neck falls somewhere in between, what are these necks comparable to? Anyone know the neck radius, nut width, or other pertinent specs? And what neck shape is this so I can know what to look for in future basses? Thanks!
