I just finished Jason's presets, and i must say they were a challenge. the Dumble clean channel wasn't too hard to figure out....Fender. but the overdrive channel required some serious thought. to be able to get insane distortion, but be able to roll back your guitar and get the same tone as the clean channel...without losing volume! insane! no wonder those amps sold for so much.

once Jason gets a chance to tweak the presets a little and make some clips, i believe many people will be surprised at what they hear.
