Blackstar St. James 4x12" Guitar Cabinet - Black - Open Box

Next-Gen Valve Amplifiers for the Modern Musician

Let There Be Light

Tone is first. Always. But gone are the days when greatness had to weigh a tonne. At Blackstar, we embrace innovation, guaranteeing you have the best possible experience every time you plug into the St. James (or have to carry it!)

Enter St. James – the lightest 50 watt valve guitar amps on earth.

Uncompromising Sound

The St. James EL34, a beacon of classic tones, marries the quintessential British Crunch with ethereal, glassy Cleans resonating with chime.

Our 6L6 variant harnesses the same pristine clean headroom and then kicks it up a notch with Blackstar’s most ferocious Overdrive circuit to date to deliver tones so brutal, they’ll make your heart race!

From Studio to Stage

With switchable power modes to bring the volume down to a sensible level, to an inbuilt reactive load that routes the post-power valve output signal to the amp’s direct recording outputs coupled with Blackstar’s state-of-the-art and fully customisable CabRig IR based DSP speaker simulator for truly authentic ‘amp-in-a-room’ feel.

No page has been left unturned and no expenses spared in the design of the St. James.

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.
