Description

The D’Addario Acoustic Cinch Fit is the fast and easy way to attach your strap to acoustic guitars with endpin output jacks. Endpin jacks are notorious for creating hassles when applying and removing standard guitar straps, and usually require modification to the strap which results in a less-than- desirable fit. The acoustic cinch fit loops through the end of any instrument strap and its cinch clamping action allows easy Application and removal, utilizing the weight of the instrument to remain locked onto the endpin so your guitar is always held securely.

    • Best answer I've found. 👍

Review Image by BrotherWind
This is an excellent answer for my needs. Acoustics with electric pick up end pin jacks are always too big around to fit a strap. The strap always twists out the end pin. I tried cutting the strap but you either make it too big or still too tight. This cinchfit solves that problem immediately and nicely. See video. I just got an Alverez AEG80CE Grand Auditorium and hated twisting this nice LR Baggs stage pro element pick up so I bought this cinchfit. Excellent! It definitely fits this pick up end pin!!! I also really like taking my strap off when I put it in my case/gig bag. I don't want the strap chaffing my lower bout sides so I've always added a microfiber cloth between strap and guitar, it's just a hassle and it grows old. But no more! This simple little cinchfit just worked perfectly from the start and I will buy another when I can for my Taylor. No more twisting the end pin and having to place a cloth between strap and guitar is very well justified, especially for the price. Sure beats the Luthier expense for repair or refinish. Fair delivery time and easily installs. Save your axe no matter what the value because it should always matter. Hope this helps you. ... show more

    • Very clever solution
Style: Original
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! ... show more

    • Works great for Gibson J45 with wide rear plug in strap nut

I use this on my Gibson J45. The plug in jack is too wide for a regular stap to fit it. So I ordered this and now I can use what ever strap I want without worrying about it coming loose.

    • Where have you been all my life?!?!
Style: Original
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! EDIT UPDATE : doesn't fit all in pen jacks ... show more

    • This is a great solution!
Style: Original
Great, inexpensive, and non permanent solution to securely attach a strap to your acoustic/electric guitar. I was hesitant, but this is the answer. Bought several for all my acoustics/electrics.

    • Took a little getting used to, but does the job well.
Style: Original
This straplock fits around the combo endpin/jack for an acoustic pickup. It allows the instrument to be plugged in while still keeping a tight lock between the strap and the guitar. I disliked it at first. The device spins easily around the endpin, which initially gave me the impression that it was only loosely secured. That was false. Turns out, this thing is so cleverly engineered, that it's a bit of a pain to get *OFF* of the end pin. Not so bad that it's to be avoided, but enough to make me confident that my instrument is secure. And because the lock device has low-friction pads and is attached to the guitar via a short nylon cord, that "loose" feeling is actually the feeling of *less* friction between my leather strap and the guitar. After having it on my expensive Larivee for a year, I just bought two more for my other acoustics. ... show more

    • Fits LR Baggs
Style: Original
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. ... show more

    • Doesn't fit all Taylors!
Style: Taylor Guitars
Works great on my Taylor 717. The 814ce though must have changed the spec. Doesn't fit. The posting doesnt specify that it only works for certain Taylor guitars. Review is 4/5 if it fits (i.e. for my 717)
