This little Vox Pacemaker changed everything I ever thought about solid state amps. Warm, smooth, and jazzy with a deep tremolo the tone was a complete 180 from what I was expecting. I tend to forget that once upon a time "Solid State" meant "State of the Art." I replaced the taped in (not grounded!) AC cable, because no amp is worth dieing for no matter how good it sounds. The input signal came to a dead end at the treble pot and I think you can tell from the photo the reason why. There's your problem right there! What started as a gamble on a cheap pawn shop find is now someone's main gigging amp.
