I bought this thinking it would do the job for my bass guitars. Nope. The part that fits the pegs is just too small. It slips out easy too.
I don't play guitar so I would never know about guitars but for bass guitars of any kind, I would not recommend. Didn't fit the paddle pegs or any other pegs, including MTD, Jerzy, Warwick, Freedom Custom Guitar Research Dulake, Sadowsky, Fibenare, etc, etc.
