I remember one of these falling off my guitar when the outer bolt came unscrewed... it used to between the washer pictured and the guitar. I experience slight static on my amplifier (even with distort/drive off) and hypothesized that maybe the missing washer was the culprit. Is there any correlation between the static and the missing washer?
probably, with the washer off the jackplug was loose so it could move around and make noise
Nut was the word I was looking for... unfortunately, the loss of the washer was quite a while back... I'm assuming I can just pick one up at a local Guitar Center?
