Walker & Williams is a long time US crafter of high end leather goods that has been in business for well over 100 years and has recently started producing outstanding guitar straps. Enough with the headaches of trying to get your strap on the input jack of your guitar. Some input jacks will rip your strap while wrestling to get it on, or worse your precious instrument could fall when your strap just pops off! We have just finished making the best adapter we can after listening to all of our customers needs. Our new adapter is made from our signature premium heirloom grain leather, and backed with a soft premium suede so you never have to worry about marking your instrument with other adapters. We cut the hole to snugly fit the standard acoustic electric input jack, with a custom aged brass W&W mushroom strap button to fit any guitar strap safely. The long time problem is over.
