Bill...I tried your settings...loved the result. Cranking up the volume gave me some nice breakup on the clean channel. If I could only get that sound at a lower volume! I also tried the settings mentioned in your second post...sounded great also. The extra breakup I got with the master up to 10 really sang. Funny thing, after a few minutes of playing at those volumes, I smelled something funny...I think it was the tubes. I put in a full set of JJ's and had it biased back in June or July, but I've never really pushed the amp (volume-wise) past 3 or 4 since then. Even before that, I still never had it up past 4.
I'm thinking that I might want to put in a different set of JJ's. When I spoke to the guy at eurotubes.com, he basically said I should go with a standard upgrade from the crappy Groove Tubes they had in there. I wanted to go with one of the "Blues Option" packages they had, but didn't risk it because one of the packages had tubes that would result in a reduction of wattage. But, I think that's what I should have went with...with the wattage reduction, the amp would break up and I could get that natural distortion on the clean channel at a lower volume. But, the tubes aren't old enough to justify getting new tube and paying to have it biased.
Thanks, sometimes I get it right
But damn chasing tone is a full days work!
I use a weber mini mass attenuator to play at lower volumes. For added gain, I use either a Boss Blues Driver, or the BBe crusher, just depending on how my ears are that day...
Good Luck and have fun
