I used to have an Ovation, but as I play sitting down all the time I got fed up with the infernal thing sliding off my thigh. Plugged in it did sound amazing, but it was like a little boy lost at a proper acoustic jam session without any amplifiers anywhere in sight.
I like those Dean acoustics too. I played one of those FM's once and it had a lovely neck for an acoustic, but I prefer the bigger, warmer sound of Rosewood over the trebley sound of maple. I'm a Bass Baritone singer so I need something with enough kick to get over the huge volume of my voice.
