I liked my 330 when I had it, but it was a little flubby with gain and prone to feedback. Generally I prefer 335 semi-hollow style, but the PRS seems to be its own thing...
You are right about PRS hollow and semi-hollows, being their own thing.
There are 3 versions of the SE Hollowbody. The Standard is mahogany and sounds darker. The SE Hollowbody II has that laminated maple sound, like a 335, only a little more alive. The 335 type, might be more flexible. I've never had feedback problems with my Hollowbody II, but I've played a lot of hollow bodies. The SE Hollowbody Piezo would be the most versatile. But I wasn't going for the round-hole acoustic electric sound. I went from Gibson, to Heritage, to Gretsch hollow bodies. So that might just be my journey. I also own a PRS, S2 Singlecut Semi-Hollow that sounds and reacts more like a full hollow body, despite looking like a chambered Les Paul. It's actually carved, not laminated.
