MusicNomad MN273 Acousti-Lok Hihnalukko

Secure Acoustic Guitar Strap Solution Without Drilling

The MusicNomad MN273 Acousti-Lok Strap Solution is a patent-pending strap lock adapter built specifically for acoustic guitars with 3-screw output jacks and end pins. It adds the safety and flexibility of strap locks to your instrument without any permanent modification, so the guitar's finish, wood, and electronics stay untouched. This model is the right choice for acoustic players who want strap-lock security without drilling holes in a guitar they love.

What Makes the Acousti-Lok MN273 Stand Out

Most strap lock systems require screwing a new button into the guitar's end pin, which many acoustic owners — especially on Taylor, Takamine, and Yamaha models — simply refuse to do. The MN273 solves this by replacing the existing 3-screw output jack plate with a solid brass adapter that already includes the strap button. Its reversible 2-in-1 button is genuinely clever: one side accepts SCHALLER-style strap locks, and flipping it exposes the QuickSecure mushroom-style button for players who just want a safer non-lock hold.

Compatibility — Fits the Most Common Acoustic Jacks

Compatibility is the single most important factor when buying a strap lock adapter, because the wrong fit simply will not mount. Engineering has been focused on the round 3-screw output jack plate used on a wide range of popular acoustic models.

• Designed For: 3-screw output jacks and end pins — the round jack plate held in place by three screws
• Compatible Guitars: Taylor ES-B, Taylor ES-Go, Taylor GS Mini (no electronics), Takamine, Yamaha — plus many other acoustics using this jack style
• The product is compatible with SCHALLER-style strap locks, which are sold separately and also work with compatible copies.

Build Quality and Hardware

Because a strap adapter takes the full weight of the guitar every time you let go, the material matters. The MN273 is built from solid brass rather than cast zinc or plastic, giving it the strength to hold an acoustic guitar through energetic performances.

• Material: Solid brass — resists bending and wear over years of use
• Finish: Black — low-visibility look that blends with most end pin hardware
• The reversible button features a 2-in-1 SCHALLER lock side and a QuickSecure mushroom side to cover both locking and non-locking needs.

Installation — No Drilling, No Permanent Changes

The whole point of the Acousti-Lok is that it installs using hardware that is already on the guitar. There is no soldering, no routing, and no new hole — just the three screws that originally held the output jack plate in place.

• Installation Steps: 3 main steps — unplug jack, route cable through adapter, re-secure with original screws
• Modification Required: None — fully reversible, the original jack plate can be put back at any time
• A low-profile footprint allows it to fit inside standard acoustic guitar cases.

Who Is It For

The MN273 Acousti-Lok is built for acoustic guitar owners who want strap-lock security but refuse to drill into their instrument. It is the right choice for Taylor, Takamine, and Yamaha acoustic players who need a non-invasive way to add SCHALLER-style strap locks or a safer non-lock strap button. Gigging musicians, touring techs, and home players find it useful if they have ever had a strap slip off an end pin mid-song.

MusicNomad — Trusted by Touring Techs

MusicNomad's Acousti-Lok line was developed to solve a real-world problem that touring guitar techs kept reporting: acoustic guitars with built-in pickup systems have no safe place to mount a strap lock. The MN273 is part of a family of Acousti-Lok adapters (MN270, MN271, MN272, MN273) designed to cover the most common output jack styles on the market. The brand's strap lock adapters have been endorsed by guitar techs working with artists such as Jason Mraz and Josh Turner, and Acoustic Guitar Magazine named the Acousti-Lok one of the best guitar accessories of 2020.
