Review: Strap adapter - Pricey, but does the job. I don’t have to team out the holes on my straps.
Review: Works well with Seagull Entourage Autumn Burst QIT - I have the dreadnought version of the Seagull Entourage Autumn Burst QIT, and while it's a great guitar, the endpin drove me nuts. It looks to be an LR Baggs metric output jack that doubles as a strap button, but it's far too wide and shallow for a strap to fit. My options were to install a D'Addario CinchFit, an Acousti-lok, or widen all the holes in my guitar straps. First I bought a CinchFit, and while it works, the strap is held on by a large knot at the end of a loop. Should that knot get jostled and slide through...well, there goes your guitar. So then I bought the Acouti-lok, which was a pain to get on, but worth it. The endpin cap just wouldn't unscrew, and after talking with customer service at Seagull, I used needle nose pliers to wrench the cap off, cupping a piece of cloth underneath it so the pliers wouldn't scratch the guitar. After that battle, the Acousti-lok screwed right in and tightened in the correct spot first-try. I tested all my guitar straps with it, and it works as well as a regular strap button would. Highly recommended.

## Questions & Answers

**Q: Does the adapter lock spin on the guitar strap peg?**
A: The adapter fits snugly. It doesn’t spin loosely but can be spun into position by hand fairly easily and it will pretty much stay where you leave it. Doesn’t touch the body of the guitar. Well made item, recommended.

**Q: Will this work on a Yamaha A3 guitar?**
A: If your Jack is metric, then yes. These devices Work on all A/E guitars that have a jack replacing the strap pin. Seller may know which model you need. If not Yamaha should or you could just unscrew the strap retainer nut go to a hardware store and find out the size.

**Q: expression system 1 taylor 814 ce circa 2004.  Will this strap lock work??**
A: I believe all you need to do in your case
is change the strap button to the strap
lock style.

**Q: Will this work with the new Schaller S lock system?**
A: I don't know for sure but it probably will with some minor modification.  I got it to work with my Dunlop locks but had to substitute the Dunlop receiver for the button that's on there.  It's a really great solution for having a strap lock when your guitar's output cable is where the strap would normally go.  It's also very solid.

### ⭐⭐⭐⭐⭐ KEEPS MY GUITAR SECURELY ATTACHED TO MY STRAP
*by P***E on August 7, 2025*

I don't understand why Taylor puts strap buttons on some of their guitars that seem to be designed to cause straps to slide off the end pin and drop your valuable Taylor guitar. I thank God that a company other than Taylor had the brains to create this perfect piece of engineering that keeps my Taylor GS MINI guitar from repeatedly dropping to the floor while I'm playing.
