I am looking to replace my SWR SM-500 head - I've had it a bit over a year and am just not getting the tone I want out of it. I play a very wide variety of styles - classic rock and blues mostly, but also R&B\funk (mostly fingerstyle with some slap). I love the Fender tones (I have a Jazz, Precision and Tribute L-2500) and play into Berg 112 cabs. I'm not really considering a pre\power setup at this point. Here is what I am looking for: 1. Tone - Warm, fat, punchy, clear. Something easy to get good tone out of. I'd rather play than tweak around trying to find a decent tone, which is one of the #1 complaints I have with my current head. 2. Size\Weight - 2 rackspaces and light to moderate weight. Again, I would rather play then schlepp around heavy gear (I also have a bad back and a small trunk). Though I like these amps, the SVTs and 400+ are out. 3. Power - The more the better, obviously. I don't think I would go below 400W and prefer 500W+. 4. Price - $1,000 or less (used amps are okay if not preferred). 5. Features - I like all of the features my SWR has. Speakon connections, xlr out w\level, mute switch, limiter, etc. The new amp doesn't need to have everything, but the more useful features it has, the better. Needs to work with both 4 and 8 ohm loads. 6. Quality\Reliability - this goes without saying. I know the right answer is to try a bunch out and get what I like best, but would love advice to get started. I'm thinking about Eden (Traveler 550) or Ashdown (EVO 500), although the I'm not sure how straightforward getting a good tone out of one would be. Mesa is another possibility. I would love feedback on these heads and any others you may suggest. Thanks for the help!
