Blackstar: St. James 100W Head

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 Next Evolution
The valve amplifier redefined and brought into the 21st century. Combining real valve tone with modern convenience, connectivity and portability, the St. James 100 sets a new benchmark for valve amplifiers.

Switchable / Mixable Valves
The St. James 100’s come equipped with two distinct power valve types: 6L6 and EL34. You can easily toggle between these valve types in 50-Watt mode or combine both flavours for a unique 100-Watt experience, harnessing the qualities of both valve types.

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.

From Studio to Stadium
With continuously variable power reduction down to 5% power, you can preserve valve tone, feel, distortion and compression at any volume.

Pro Connectivity
USB for pure valve tone in your recordings. XLR CabRig for stage brilliance without mics. And the 1/4″ output for that driven valve amp bliss through your headphones. A trifecta of sonic freedom.

Revolutionary Speaker
Collaborating with Celestion, we pioneered the extraordinary Zephyr lightweight speaker. Like a Formula 1 race car, we stripped back unnecessary weight, resulting in a lightweight speaker that still uses a traditional Ferrite magnet.

Lightweight With No Compromise
Candlenut plywood is used for strength, lightness and its beneficial acoustic proprieties, creating a roadworthy cabinet that sounds great and will last a lifetime.

Universal Voltage
Combining modern SMPS technology for lightweight and universal voltage compatibility with the classic feel and response of traditional iron-core transformers, this innovation is poised to set new benchmarks for valve amplification.
