i own a C7 Diamond Series, and the neck profile is nice... it's not at all like an
Ibanez neck, if thats what you're wodnering. It's thicker than a UV neck, and not as flat, either. It's thinner than a Strat neck, but still thicker than an Ultra neck. Actually, it's a bit like a Viper or Ultra neck, now that i think about it.
Hope that helps!!!
Oh yeah, the Dillion 7-strings are amazing!!! And cheap, too.
