Which of the above would suit me best? I have no problem carrying around something heavy, so weight and portability isn't really an issue. I'm looking for something around 200-500 watts, solid state equivalent. I'm planning to use a single 4x10, possibly an Ampeg 4x10HE. I use a 4 string so immense low frequencies aren't a huge deal. It's an active Jazz. Basically, I'd want some tube warmth and growl, but no mud. The Ashdown EVO 500 was incredible through an Ampeg 8x10 when I tried it today, basically the sound I want. The V-4 is a little bit darker, but still a good choice... although it is a big weaker and less versatile (but slightly cheaper, and the only amp of the above I can hope to find used around here). The Yorkie is pretty decent but seems too solid state... I had trouble getting a good tubey tone out of it. And I have no experience with the Walkabout, just heard great things. Which would suit me best? Thanks in advance.
