I've got a Mesa 50/50 poweramp sitting around that I've considered selling, but I'm also considering keeping it and pairing it with a preamp for another "flavor" of tone to use. My main rig is, of course, the MP-1 through the 2/90/2, but MOAR gear = MOAR TOAN!
The Studios seem to go for pretty cheap on eBay compared to the Triaxis, and if the Studio gets the same badass Mark style tone then I wouldn't really care about the Triaxis bells and whistles. I've grown away from the Recto sound quite a bit, but I've never gotten to play through a Mark. I loved the DC-5 that I played.
So, lets chat about them and other preamps, and perhaps one of you should give or buy me a Bogner Fish? That would be super cool. I'd take you out to dinner. Burritos by candle light? It'll be romantic.
And again...window shopping...building GAS lists....
They're pretty Mark-ish, yeah, especially with the right EQ settings. I've always liked their tone. It can't hurt to try it, given that you'd probably get your money back out of it if you didn't like it.
