For example, I've tried a Fender Jazz V, Stingray 5, Ibanez BTB405, and Peavey Cirrus 5. The Fender and EBMM had pretty round necks, but the Ibanez and Peavey necks felt pretty "flat," if you can understand what I'm saying. It was more like a rectangle profile than an oval, I guess. In any event, what basses have flatter necks like this? I'm not really concerned about nut width or anything, I just thought that those flatter necks were pretty comfortable.
