D'Addario CinchFit: Acoustic Jack Lock

This thing works well on my Gibson L00. The end-pin is too wide and it doesn’t stick out much. CinchFit is the way to go with this type of end-pin

I’m pleased with the Jack Lock device from D’Addario. It is reasonably priced and well made. It fits my end pin jack from LR Baggs, but it was a little loose so I added a small piece of painters tape inside the circle clamp ring to snug it up on the jack rim. It still rotates freely, but it is more solid and makes less noise that way. What would a man do without painters tape?? Anyway I’m happy with it.

Works perfectly to hold my strap well and over my jack/pickup. It DID loosen and fall off one time. Fortunately my guitar was in my lap. Added "Loctite" to the threads.

My GS Mini and Academy 12e-n (both ES-B) have endpin strap buttons with 2 screws that are not flush and protrudes, preventing both pieces of the jack lock to sit flat and attaching properly. Description should indicate which ES fits but does not. One of the two Taylor models I ordered, a rubber piece on one side was completely missing. I also have the original jack lock on an Epiphone PR-150VS and a Cordoba GK Studio and they seems to work fine. If your Taylor endpin looks like mine in the photo, it will not fit. No photo of jack lock with it. Items were returned before this review.

This is such a clever solution to the problem of straps fitting around the output jacks of acoustic guitars with pickups. I previously used a knife or scissor to expand the opening of guitar straps, which worked but was still hard to squeeze on to the jack plus didn't feel as secure as I wanted. I considered the Acousti-Lok system but that requires using Schaller strap locks and sometimes doesn't fit well in hardshell cases, so I thought I'd give this a try first. Gotta say, it's so easy to use and remove, and it just works!

clever way to add strap to electric instrument. Works great on my tenor ukulele

They're OK, but I wouldn't trust them in a real pro music setting. They do slip open. My guitar has fallen out. It's amateurish. OK for home studio stuff I guess.

I'm a fan of lock-it straps but they don't fit over most of my guitars that have endpin jacks. I'm always uncomfortable that other straps that do fit over endpin jacks are gonna slip off, because they have. This thing makes me feel secure that my guitar is not gonna come loose from the strap. It gives me the "where have you been my whole life" vibe. Simple, but brilliant. It works!

Façon très pratique pour attacher une sangle. Ça tient très bien et ne gène en aucun cas le branchement

I have a lovely Martin acoustic that has a pickup installed where the jack is built into the strap button, and wasn't confident the nice leather strap I have would hold even if I managed to get it over the large strap button. This has been a rock solid solution that is incredibly easy to fit while being secure enough to gig with. Highly recommended.

It does the function very well. Ignore the comment that it comes off easily; it will come off if that's what you're trying to do! It won't come off while playing! Best way to save your straps from stretching the hole end.
