Product Information

Blackstar Amplification is proud to introduce the St. James 112 – a groundbreaking 1x12 cabinet that combines uncompromising power with unmatched portability. Delivering a full 100 Watts through a custom-designed Celestion G12Z Zephyr High Power speaker, created exclusively for Blackstar, the St. James 112 is the ultimate solution for modern players demanding both sound quality and portability from their rig.

Constructed from candlenut plywood – a material Blackstar has advanced in the guitar cabinet world – the St. James 112 offers exceptional durabilitywhile remaining featherlight. Weighing just 12.8kg/ 28.2lbs, it’s tough enough for the road yet effortless to carry, making it equally at home on stage, in the studio, or rehearsals.

Developed in close collaboration with Celestion UK, the custom Zephyr High Power speaker took over a year of refinement to perfect. By pairing a traditional ferrite magnet instead of neodymium with lightweight engineering, it delivers the rich, dynamic tone players expect from a premium 1x12 cabinet while safely handling high-powered
amplifiers without compromise.

With its illuminated Blackstar St. James logo, 16 Ohm input for universal compatibility and compact footprint, the St. James 112 is a forward-thinking cabinet designed for today’s gigging and recording guitarists. It’s perfect for partnering with pedalboard amps or valve heads, like our AMPED range of 100W pedal amps, or our St. James 100 valve head – the world’s lightest 100W valve amp. Whatever your use case it provides raw power, refined tone and road-ready resilience in one lightweight, portable package.

More and more players are downsizing their rigs without wanting to sacrifice tone or projection. The St. James 112 delivers everything a guitarist could want: lightweight design, premium construction, and the ability to handle 100 watts of power with ease.
