I spend alot of time at a music store that is a Crate dealer.....
BTW...I've only listened/played with this head through the 2 4/12 cabs Crate sells as a set.
Plenty of volume, way more than I'd ever need. Good harmonic response-pulling out Zack Wylde type squeals is real easy...
Reverb is ok when used in small amounts.
Go try it....you'll probably like it, especially if this is your first 'big' amp.
