I am in the market for a new amp. I currently have an Ampeg SVT-350 50th Anniversary Edition head and cabinet. I like the head but it is too heavy and not rackmounted, which makes it difficult to transport. Also, from years for unprotected travel to and from gigs, it has become a bit unreliable. I know people ask questions like this all the time, but I would like your input on my next amp. I would like something rackmountable, powerful, and fairly light. I am keeping my Ampeg cab and the Hartke 2x15 I own. Both are 8 ohm. I play a range of styles, but my two current projects are rock/pop and hip-hop. I would like to get something for no more than $1000. So, any suggestions? Thanks guys!
