Oh, it has outrageous curl, that's for sure. But what it really has is tone. Unlike many maple guitars which can sound sterile or shrill, it has a wonderfully open tone with the almost contradictory qualities of incredible depth and crystal clarity. It's open, loud, balanced, focused, mature....it just goes on and on. It's a grand concert sized guitar with Nick Lucas depth. It's like having the best of dreadnought and OM worlds at the same time.
The AC-610 is no longer listed in the current catalog. That's too bad. I'm glad I got my hands on this one.
