Problem with a capo
I often play my acoustic guitar with a capo on it, and towards the end of a gig I put the capo on and it sounded terrible. I tried putting it on a few times on different frets but it always sounded very very buzzy, it sounded like some strings weren't even being held down at all. I assumed something had broken in my capo even though it looked fine. I got home and tried a different capo but I encountered the same problem.
Any suggestions of why this could be?
