I don't have an A30, per se, I have the previous model, the SE Angelus Custom. Same construction, except I believe the A30 has laminate sides instead of the solid sides the older model has.
The rosewood gives it a nice tone, very warm and sparkly - the way I've come to describe it is that is has a nice mid-range cut, sort of opposite what mahogany does. (Which is why I bought a second guitar completely different from the Angelus Custom to get a brighter/punchier tone for certain applications.)
It is loud enough when playing chords, but not boomy. Very nice sound plugged in, great sound recorded in the studio.
I can get lost in the mix when playing leads if we play truly unplugged (thus my other guitar - it is louder/punchier for single note stuff).
It plays very nicely - I like the ebony fretboard, smooth, a little "quicker" for me compared to rosewood.
And I like the neck profile - 1 21/32" is a really nice size for my hands. Some folks may prefer a wider neck, the more traditional/typical 1 3/4" of other major brands (although they offer thinner necks too, especially on the lower cost models).
