i'm looking to get a ampeg b2r or a swr 4004.... right now i'm playing rock on a hartke, 200watts thru a hartke 4X10 cab. its not bad. i want an amp thats is very transparent. so i'm looking to improove my gig a bit and the gear i'm playing now isn't mine.. here are the 3 options i'm thinking about: buy a ampeg b2r buy a swr 4004 or by a ampeg preamp and a quiet power amp let me know what you think. and if you think any of those options would be much of an improovement. thanks!
