I really would like to be able to run my Champ "opened up" but at a non-ear-splitting volume (neighbors, tinnitus, etc., et al, ad nauseam) and am considering an attenuator. I was looking at the JHS Little Black Amp Box. It requires no power. One of the descriptions said to put it in an effects loop, but obviously, the Champ has no such thing. Anyone use one of these? Could it work on the front end of an amp as well? Any other suggestions for simple, compact, low-cost attenuation?
