I dont have one, cause Im not really that into clean tones, most of my stuff is dirty sounding, but Ive played thru them before, they also made a JC-90, which is a bit smaller, and pretty damn loud
I play a Mesa Triple live, for my clean tone I back the gain off on my clean channel and crank the master, my eq's are around the mid position, but I tinker with them all the time, but what I did was did out this old Boss CS-3 compressor I have, and put it in front of my amp, basically I use it to boost the clean tone and roll the volume on my guitar way back and adjust eq at the guitar, I use a les paul, so its a little brighter than a strat anyway. But I use the compressor as a booster, to level out the level on the clean to match my dirty channels.
But then again in a 4 hour gig, I dont use the clean on a few songs, so its not really an issue with me
Good Luck
