My reverb cables on my SF Twin Reverb were giving me trouble. I would have to jiggle them to get the reverb to work. The jacks appear fine, the cables were in pretty rough shape though. I ordered some new reverb cables and installed them today and now the reverb doesn't work at all! I hooked them up correctly and double checked everything. The reverb was working yesterday. I can't put the old cables back on because they fell apart when I disconnected them.
