I'll play. Sort of.
I know MT himself is a V30 guy, and I've gotten good results with V30's, but not the best. The MT15, like the other 2 channel PRS amps I've tried, is not a very bright amp, and with V30's can range from smooth in a good way, to downright dark sounding. With V30's I found that I had to go bass 9:00 (or less) mid 2:00, treble 2:00, presence 3:00, just to get it to "bite" on the top. I run mine more with my "old" PRS SE 2x12 cab (from the previous generation of overseas PRS amps) and something about those speakers makes the amp more versatile. They have mids and bite like a (very angry) Marshall through a greenback loaded cab, all the way to Recto reminiscent stuff with less mid dialed in. Somewhere in the neighborhood of bass 9-10:00, mid 12:00, treble 2:00, presence 12:00. I also much prefer the clean with the SE cab, the V30's require running the treble up to a point where the tone gets thin, but any less and there's no sparkle, a very fine line. Perhaps its the cab I'm using, or the V30's which I bought from Avatar and were cheaper than anywhere else...
