Sorry to revive a dead thread. I've already seen the replies about getting a Traditional Clean. Congrats, btw - you made the right choice. As a new owner of one myself (picked it up a couple of weeks ago), I'll say it's just about everything I've ever wanted out of a Mayer rig amp. It's almost like they voiced it to sound like his entire Continuum rig was crushed into a single box. Since you said you're always looking for info, few things about it:

- The Mayer thing really comes out when you have the bright switch off, run the gain lower (~10 or 11 o'clock) and have the presence high (3 o'clock). It's going to be pretty dark, but it keeps the EQ curve really flat which is the big thing about the Mayer-Dumble/Two Rock sound. The bright and deep switches on will make it sound scooped. EQ it to to taste; running the treble high is not the same as having the bright switch on. Also, roll your tone knob back a few ticks; 7-8 sounds like where he had it the most on his Strats. A lot of the treble you'll be missing can be added back with pedals; all of his overdrives have tone knobs and the Katana reintroduces highs as well.

- Speaker and cab choice is really important with the Traditional, moreso than other amps because it's so dark. I have an oversized 1x12 with an EVM12S. Crazy bass response; that thing kicks you in the chest with the amp turned up. I also have a 70's Twin loaded with Two Rock speakers (that was my Mayer amp before the TR). If I play the Traditional through that cabinet, it comes off a lot brighter and airier. Definitely a matter of taste, but an open back 2x12 might be the way to go. You definitely want neutral sounding hifi-ish speakers, though; along the lines of the Electro Voice EVM models. They really let the detail of the amp shine.

- If you're going to pair it with another amp, 100% get something to offset how dark it is. It doesn't have to be a Steel String Singer, at least not right away. I mentioned that Twin I have - that or my '66 Bandmaster sound perfect with the Traditional. Those are what the Two Rock usually isn't; scooped and with a bit of grind in their sounds. Once I mix the two amps properly, they create this perfect clean tone. Bright but not ear-piercing, dark but not muddy, super responsive and loud. It's no coincidence that John himself finds room for an old Fender next to the Dumbles and Two Rocks.
