Hi, all. I recently purchased a used 65 Deluxe Reverb Reissue. Sounds great, but there seems to be an issue with the vibrato channel. As I understand it, the vibrato is not supposed to function without the foot switch plugged in. That isn’t the case. The only way to turn it off is to drop the intensity and speed down to 1. It works like that without the foot switch plugged in at all. Plugging the foot switch in makes the oscillation of the vibrato much noisier and the foot switch does not turn the vibrato off. Reverb switches on and off just fine. Tested the FS with a multimeter and everything is fine on that front. I’ve seen similar threads to this, but no definitive solution. In the grand scheme of things it’s not a “bad” problem to have. I can turn the knobs down to turn off the vibrato effect. However, it would be nice to be able to turn it on and off within a song, or just simply understand why it isn’t functioning properly. Thanks for any insight!
