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.
Their AT-2 Headstock Adapter is a humble but extremely useful accessory used for attaching a guitar strap to the headstock of an acoustic guitar that does not have a strap button in the heel of the neck. This is the way all acoustic guitars were traditionally made for centuries and the way many guitars are still being made today, Martins and Guilds for example. These headstock adapters are also commonly used on all kinds of other instruments that need a place to attach a strap, such as Dobros, mandolins, bouzoukis and ukuleles.
Please note that the AT-2 is both longer and thicker than most other headstock attachments that are available. As a result, it will work just fine out of the box with the typical guitar strap that uses a single thickness of leather for the end caps, but until it’s broken in and softened up, it can be a challenge to use this with a strap that has doubled up or thick padded end caps, which actually includes most of the Walker & Williams straps.
Because the full grain carving leather they use for this accessory is quite thick and stiff, it will take some time to break in, like a stiff pair of new boots. But like the new boots, it will soften as you use it over time, form itself to your guitar and should then last just about forever.
