I've had that experience several times playing with different people, and a lot of them in signed bands with really nice equipment. I've put my Triple up against Kranks, Oranges, Bogners, Hughes and Kettners, Splawns, Marshalls, Crates, Fenders and others, and I've not once heard tones that compete with my amp in the sound I can get out of it for the music style I play. I'm always complimented on how my tone just slays, and I just point to my amp with a grin on my face. It's also nice whenever my band does play with other bands that have Mesas, and all of them are usually Dual Recto owners, I stand out first of all because I have a Triple, and second because I am always the only one with a black faced/chromed chassis model. They always ask me where I got it and sulk, saying the should've done that because it looks so much better than theirs lol. I recently played with a band that had a guitarist with an early 2 channel Dual Rec with a small logo, i think the serial number was in the early 1000's, sounded good, but with the JJ's I have in mine, I could get my Triple close to his tone, but by having three channels, I had a lot more flexibility when it comes to having a true clean channel and two different distortions. That's really nice when you have two guitars with different voicing and require a little different eq-ing.
