I am the proud owner of a 1984 JCM 800, have been for about 8 years. Only thing I will ever use. I am wondering, however, what kid of mod I would do to get a little distortion. Amp has only gain, which sounded righteous with my les paul, but I recently picked up a 1981 Ibanez Artist, and would like a little more bite. Any suggestions, or am I being blashphemous even asking?
