all of my mods clean up nicely. I may have to max the master on them but when set right, they all produce excellent cleans, if not just about to break up sounds.
C-Watt being the most clean, then the Super Vox, then R50, then Stoner AD, in that order. My Les Paul seems to want to dirty up everything with the BB pros. Can't stand them. My SG with 57 classic and a T-top stays nice and clean and the strat is always clean
The C-Watt starts to beak up in DR mode with gain just below half, R50 Gain at 1/4, Super Vox Gain at just over 1/2 in AC30 mode, Stoner Gain at 1/4 to 1/3, it also has the Natural channel which is totally clean except when driven by a pedal, warm and clean.
All of these settings produce nice punchy cleans. i can even get the C-Watt to sound Fenderish with 6L6's in there
