I assumed it was only me, but looking around the internet this appears to be a common problem among teles: the pickup switch know just fells off. All. The. Time.
I found this tip (a lot of videos with it) but I couldn’t quite make it work.
Any other advide/solutions to this minor but annoying issue?
Cant say its ever happened on my tele ( touchwood ). I was always hitting mine initially, till my strumming shortened up. Wonder I didnt knock it off.
What about a sliver of paper, or similar? Visit to the guitar shop for another better fitting one? I’d be avoiding the glue route.
The pincers idea is good for a plastic knob, but do it a bit at a time until you get a reasonable grip that’s not too difficult to get off. I had a metal knob with a grub screw made that was anodised gloss black, end of problems!
Problem is that if it’s tight enough when you push the knob on the tape moves, anything you put in there unless it’s fixed will move before you get a decent wedge effect. At one point I did superglue a thin wedge of wood on the switch blade but it’s got a tendency to split the knob if it’s too thick (no don’t ask how I know ).
