Not even remotely a good deal. Man when it comes to Mesa Boogie, I've learned over the years that there are basically three things I like. First, unless you want a Mark V or JP2 for the versatility, etc... the best damned Mesa Boogie sounds come out of the Roadster, Lonestar, and Express 5:50. I tell you, I have sat the 5:50 down next to so many other Boogies, and as much as I wanted to stay skeptical because of the price difference, that damned amp delivers the tone. The Roadster has that one channel with the British mode that kills, and you can live on that one mode alone. Then the Lonestar is like a different island.
So when I see old Boogies going for $3,000, I see the same old-ass amps like the scraped up Fenders with $10,000 price tags at Guitar Center. I could care less about spending the bucks on an amp that will probably need new caps or some other maintenance. I saw a better condition Mark III with flame wood cab that looked new and still had the tags for $1200 just about two years ago, so I don't know where he gets his price. Plus he puts "NO LOWBALL OFFERS" in big letters as if he's barely going to negotiate the price. Unless you're rich enough to wipe your ass with money, fuck that deal.
