Chuck Ragan

Chuck posted picture of this amp on his instagram, so I guess he uses this model too

I also have a Tiny Terror Combo which is one of the greatest things since poly urethane skateboard wheels!

I mostly play through the Orange Rockerverb 100 MKII through an Orange Closed Back Cab w/Celestians.
