Yes, I did the tube swap to tame the red channel a bit. I still only run the gain on that channel at about 11 o-clock even then. It evened out the sweep a little so now the usable gain is in a better range and it seems slightly more open.
The other cool thing is this has a mod done by FJA Mods that adds concentric pots on the pre and post gain for the green/blue channel so you can control the gain and levels independently on those channels. Really helps with balance the volume on those two channels with no compromises.
As much as I love the amp I find myself gassing just a bit for the new Mesa Triple Crown. If I get a chance to try it out I will, but I have a feeling that could be dangerous!
