I just got an old 18 volt Danelectro cool cat chorus off ebay. It sounds great in my stereo amp setup. The only problem with the pedal is that it seems to cut out on long sustained notes. Its really bad when the guitar volume is rolled back. I read though some Harmony Central reviews on it and a few people mentioned the same issues in both the 9 and 18 volt versions. Has anyone found a way to correct this in their pedal?
