BGM

Brand: JOY EDC
Product Name: BGM

Features
Slide Side

The slide side features the signature **BGM half-stroke automatic track-switching system**, allowing seamless switching between two sound profiles with a simple half-stroke—**no disassembly or adjustment required**.

Effortlessly switch between a **segmented crossover click** and a **dense, crisp ringing tone**. The modular design also supports a variety of DIY configurations for users who enjoy customization.

**Note:** When using the slide side, do **not** install springs with a wire diameter greater than **0.3 mm**, as excessive spring force may deform the POM slider.

Rotor Side

The rotor side combines two distinctive rotor designs:

* **Ringing Rotor** – Produces a sound signature that is different from the slide mechanism. It can also be customized to create either dense crossover sounds or segmented ringing tones through disassembly and reconfiguration.
* **Buckyball Rotor** – Delivers surprisingly strong tactile feedback despite its compact size, while producing a unique sound reminiscent of a miniature speaker system. This rotor was developed under the guidance and authorization of **OS Terence**.

To further enhance both aesthetics and craftsmanship, the BGM features **precision-machined engraved titanium magnetic screw covers**, concealing the mounting screws for a cleaner appearance.

PEI Version

Features

The **PEI Edition** retains the classic **BGM half-stroke automatic track-switching system**, allowing instant switching between a crossover click and a dense, crisp ringing tone without disassembly or adjustment.

The redesigned track return mechanism produces a **louder, clearer sound** than the metal version while delivering stronger tactile feedback and a more positive sliding action.

The rotor side features both the **Ringing Rotor** and the **Buckyball Rotor**, now manufactured from **imported PEI**. The internal track geometry has been refined through **more than a dozen design iterations**, resulting in smoother operation, improved consistency, and enhanced acoustic performance.
