[CAUT] Funny Noises

Ken,

Question. Does it still have the original wippens? If so, isn't this 
vintage teflon bushed? I know our 1972 L's are. So you might check that.

One other "wild guess". Is the end of the rep spring that goes into that 
hole in the back of the jack too long and 'rubbing' on the jack creating a 
click?

Good luck. Let us know what you discover.
