▪ Like you might have heard, it is possible to locate a buzzing fret on a guitar that uses metal strings by exploiting the fact that an electical connection would be made when the string briefly touched the fret. It can be hard to see a flickering light or see a response on a VOM. This little project is optimized to make that contact visible and audible.
