Multivox Big Jam Compressor from the 1980's/MIJ, missing battery door
These are known to have iffy footswitches, and this one is no different. I'd say it clicks over about 65% of the time. Good thing is that you don't typically toggle compressors on and off, so once it clicks over you can likely set and forget it. Missing battery door, sliders have been cleaned, and the rubber pad has been reglued once before, you can see bits of glue around the rubber pad area. Simple to use, sounds great, but please again note that the footswitch might take a few hits to switch from bypass to effect.
