This article covers Glorious GMMK PRO 75% Barebone ANSI USA Black Slate カスタムキーボード ベアボーン GLO-GMMK-P75-RGB-B KB615.

Overview

The Glorious GMMK PRO 75% Barebone is a custom mechanical keyboard kit designed for enthusiasts who want full control over their build. It features a 75% layout (82 keys) that strikes a great balance between compactness and functionality, retaining the function row and arrow keys while saving significant desk space. The board uses an aluminum top plate and gasket mounting to deliver a refined typing feel with consistent flex. As a barebone kit, it ships without switches or keycaps, allowing you to choose every component. The hot-swappable PCB supports both 3-pin and 5-pin switches, making it compatible with virtually all Cherry MX-style mechanical switches. Connection is via a detachable USB-C cable. This is a popular starting point for first-time custom builders and a solid upgrade for anyone wanting a premium typing experience without the soldering.

Connectivity & Compatibility

The keyboard connects to your PC using a detachable USB-C to USB-A cable (included). The USB-C port on the keyboard allows for easy cable swapping. Compatibility extends to Windows, macOS, and Linux, though the dedicated Glorious CORE configuration software is available only for Windows and macOS. A web-based configurator is also available for basic adjustments. Switch compatibility is broad: it supports all standard 3-pin and 5-pin Cherry MX-style mechanical switches, including popular options from Gateron, Cherry, Kailh, and others. Keycaps must have a standard Cherry MX cross stem; most aftermarket keycap sets will fit. The keyboard uses a standard ANSI layout, so replacement keycap sets are widely available.

Product Info

The GMMK PRO 75% Barebone was released in late 2020 and is widely available through Japan and other authorized retailers. Typical retail price is around ¥27,000–¥30,000. The kit comes with a 2-year warranty for units sold via the official Japanese distributor. Included accessories: USB-C cable, switch puller, keycap puller, and quick-start guide. Market positioning: it occupies the mid-to-high-end custom keyboard segment, offering gasket mount construction, hot-swap sockets, and a perfectly proportioned 75% layout at a price that undercuts many boutique alternatives. It remains a strong value pick even years after launch.

Best Use Cases

First-time custom keyboard builders – The barebone format removes the complexity of soldering while still allowing you to select switches and keycaps.
