I weep everytime I recall my father selling his '65 SG. His complaint: The neck was too thick.
He replaced it with a Moserite, skinny little neck thing. Grrrrr...
If I ever get through a tax year without owing my greedy Uncle Sam, I'm buying a Gibson. OR... I may just build one myself. I played a friend's custom strat with a Warmoth neck. That neck was like holding a half a Louisville slugger. <drool>
I don't really play in a bluesy style. I can, or at least used to be able to, shred on the larger necks. I tend to have a heavy hand, so I have had a problem with thinner necks being unstable. Only my Jackson was really stable for a thin neck. Granted it had 1/4" of ebony over maple. Of course, I haven't played everything, so I can only speak of what I have played. I'm sure that there are many modern guitar necks that are thin and stable. The older Ibanez's(pre-'85 or so) were really nice, too. They mimicked Gibson back then.
