Blackstar Introduces St. James 100 Head and Combo

Designed with versatility and innovation at its core, the St. James 100 features four channels and six modes, alongside a suite of cutting-edge connectivity options


Blackstar Amplification has introduced the St. James 100 Head and Combo, the company’s flagship series in valve amplifier technology.

These include a built-in reactive load, CabRig IR-based speaker simulation, MIDI control, and USB-C connectivity making it the ultimate tool for the gigging professional and studio player alike.

Continuing the legacy of the acclaimed St. James series, Blackstar’s St. James 100 Head is the world’s lightest 100 Watt valve head, while the St. James 100 Combo claims the title of the lightest 100 Watt2x12” valve combo. By blending traditional craftsmanship with modern technology, these amplifiers set a new standard in high-performance amplification.

The St. James 100 introduces a suite of groundbreaking features that distinguish it from the competition. At its core is the innovative switchable and mixable power valve configuration, which incorporates two distinct power valve types, 2x 6L6 and 2x EL34. These can be toggled between or combined using a front-panel switch, allowing players to select 50-watt operation for specific tonal flavors or engage all four valves for the full 100-watt experience, unlocking a wide range of tonal possibilities.

The amplifier also features continuously variable power reduction, enabling the output to scale down to 5% of its maximum while preserving the signature valve tone, feel, distortion, and compression, making it ideal for any environment. Adding further versatility, the patent-applied-for ‘Cut’ selector offers a 3-position toggle to fine-tune the highest octave audio range (10kHz–20kHz) at the speaker outputs adjusting high-end frequencies for anything from aggressive clarity to warm, vintage tones.

The effects loop is equally flexible, switchable between +4dBu and -10dBV for compatibility with professional or stompbox-level devices, and offers both series and parallel routing options.

Additionally, a rear-mounted potentiometer provides fine control of the foot-switchable Solo Boost, adjustable between +2dB and +6dB, ensuring you get the kick that you need for standout lead moments.

The St. James 100 is a testament to Blackstar’s dedication to pushing the boundaries of amplification. With one patent secured and another pending, this amplifier showcases the ingenuity of Blackstar’sengineering team and delivers groundbreaking solutions for guitarists worldwide.
