I have it set up with a 1x12 K120 cab, and MosValve 962.
Playing along with a few YouTubes, it sounds great!
It is a JG1 model.
It has "Arnold's Carnival" written on the top???...(anybody???).
it appears to be working perfectly, and arrived well packed from GC.
I was just messing around with Mattsons settings from a DSO vid of China Rider.
Kudos to Brad!
