Blackstar proudly presents the St. James 100 combo, 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 combo is the world's lightest 100-Watt 2x12” valve combo, blending traditional craftsmanship with cutting-edge technology.

The St. James 100 combo 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 combo 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.

Dressed to Impress
The St. James 100 combo exudes elegance with its sleek, all-black design, perfectly balancing modesty and allure. The illuminated logo adds a striking touch, ensuring this amp stands out while maintaining its understated charm.

Easy install, wide and sturdy

I put these shelves in a strange little cubby that was created in my kitchen by removing the sad excuse for a pantry that was once there. Super easy to hang, I’ve only hung two here and have other plans for the 3rd one. Good purchase for sure. Very sturdy and look expensive, without the high cost.

Great shelves!
Size: 12"D x 35.4"W, Color: Black
These were perfect for what I needed & easy to install with included hardware; looks great and looks like quality item. I like that they will hold 20 lbs so I can change what I place on them with no worries.

Sleek and attractive
Size: 12"D x 23.6"W, Color: Black, Size: 12"D x 23.6"W, Color: Black
While these didn't come in the color I was looking for, the size and price point were just what I was looking for. Installing them didn't take too long and was simple enough, but the end result did seem a little more wobbly than expected. I used them to display mine and my boyfriend's boots, and they held up fine, but I think 22 lbs per shelf would be pushing it. I was able to easily cover the shelves with wood grain look contact paper and easily trim the excess off with an Exacto knife to get the look I wanted. I'm happy with how it turned out.
