Blackstar proudly presents the St. James 100 head, a groundbreaking evolution in valve amplification. This amplifier is one of our most ambitious projects, painstakingly developed over the past few years to deliver unmatched valve amplifier performance.

Continuing the legacy of the St. James series, the St. James 100 head is the world's lightest 100-Watt valve head, blending traditional craftsmanship with cutting-edge technology.

The St. James 100 head boasts a range of innovative and unique features that distinguish it from the competition:

Versatile Power Valve Configuration
The amplifier comes equipped with two distinct power valve types: 2x 6L6 and 2x EL34. With a front-panel switch, you can toggle between these power stages in 50-watt mode or combine all four valves for the full 100-watt experience, offering unmatched versatility in sound.

Revolutionary Power Amplifier “Cut” Selector
For the first time, Blackstar introduces a switchable “Cut” selector. This PAF three-position selector allows you to fine-tune the amplifier's higher, harsher frequencies. This customisation lets you shape the amplifier's overall sound to perfectly match your preferences from an aggressive, extended high-end to a warm, vintage sound.

Advanced Connectivity and Tone Control
The St. James 100 head includes a built-in reactive load and Blackstar’s IR based CabRig technology, providing professional direct tones for both live performances and recording sessions. The amp also features a switchable effects loop (Series or Parallel) and an adjustable +2 - +6 dB Solo boost which is controlled via the included 6-way footswitch.

Modern Aesthetics with Classic Appeal
While the new design aligns with the St. James lineup, it also introduces a fresh look that showcases the internal valves. This design dispels any doubts about the amplifier's valve driven nature, despite its lighter weight and advanced technology.

Experience Unmatched Power and Flexibility with the St. James 100
Level up your sound and unleash the raw power of the St. James 100 head. Whether on stage or in the studio, this amplifier is your ultimate tool for self-expression.

Can’t say enough love
I got the trio set and I absolutely love this line. My face is so soft and hydrated. It doesn’t irritate it and I have very sensitive skin. This is hands down the best skin care line I have used!
