I just got back from Juan's place with my EV 215 cab and an Ashdown EVO-II 500 watt head. I was origionally going to get a used 400+ head, but when Juan and I plugged it in it started crackeling. So I ended up with the Evo. I'd have to say this is a decent to good head- 500 watts at 4 Ohms, fairly versitle. I love the EQ on this thing. The preamp is good as well. However, I love tubes and it looks like I'm going to be saving for a Fender 300 watt tube sometime near the end of the summer. Oh, the cab is so awesome! Love the cab. It has better highs than I expected with its 6" high driver.
