These work well- though make sure you're getting the right mount type. I didn't notice the two-pin configuration, so installing will require that I drill some holes. It's not a big deal in my case, but double-check what you already have.The tuners are a great value, considering they're not much more expensive than non-locking ones. The stability and ease of use you get from locking tuners are always worth it to me.These also are finished nicely (I got the chrome ones), they look good, and the mechanics work well. Overall, a good buy.
