Overview

Experience the pinnacle of valve amplification with the Blackstar St. James 100, a groundbreaking evolution in guitar tone.

The Blackstar St. James 100 head represents a new era in valve amplifier design, meticulously crafted to deliver unmatched performance and versatility. This amplifier, a culmination of years of research and development, blends traditional craftsmanship with cutting-edge technology to create an instrument that's as powerful as it is innovative.

Uncompromising Valve Performance with Unmatched Versatility

The St. James 100 head boasts a range of unique features that set it apart from the competition. Its versatile power valve configuration allows you to choose between two distinct power valve types—EL34 and 6L6—or combine them for a total of 100 watts of pure valve power. This unparalleled flexibility allows you to tailor your sound to any genre or playing style.

Revolutionary "Cut" Control and Advanced Connectivity

For the first time, Blackstar introduces a switchable "Cut" selector, providing precise control over the amplifier's high-end frequencies. This innovative feature allows you to shape your tone from aggressive and cutting to warm and vintage with the turn of a knob. The St. James 100 head also features a built-in reactive load and Blackstar's IR-based CabRig technology, delivering professional direct tones for both live performance and recording.

Four Footswitchable Channels and Comprehensive Tone Shaping

With four footswitchable channels, the St. James 100 head offers a wide range of tonal possibilities. Each channel is meticulously voiced to deliver classic Blackstar tones, from clean and pristine to high-gain overdrive. The amp also includes a footswitchable effects loop, a variable power reduction down to 5%, and a master volume for precise control over your sound.

Modern Aesthetics with Classic Appeal

The St. James 100 head features a fresh new look that proudly showcases its internal valves, leaving no doubt about its valve-driven heart. This modern aesthetic, combined with classic design elements, creates an amp that's both visually stunning and sonically exceptional.
