The Blackstar St. James 50 EL34 Combo is a groundbreaking 50-watt valve guitar amplifier that sets a new standard in tone, feel, and portability. Traditionally, high-wattage valve amps have been heavy and cumbersome, but the St. James series changes the game by offering the lightest 50-watt valve amps available. Through extensive critical listening and comparisons with legendary amplifiers, Blackstar has created an amp that delivers exceptional sonic performance.

The St. James 50 EL34 Combo excels in producing classic tones, from world-class British crunch to impressive, American-style cleans. It features cutting-edge technology designed to enhance both live performance and recording. Switchable power modes (50W, 2W, and SAG) allow for versatility, while the inbuilt reactive load enables direct recording through XLR, stereo line-out, and USB outputs, all with a genuine ‘amp-in-a-room’ feel, thanks to the advanced CabRig™️ DSP speaker simulator.

The amp also boasts professional connectivity options, making it ideal for home recording and silent stage setups. It includes USB audio connectivity and an XLR D.I. output, utilizing the inbuilt reactive load and CabRig DSP speaker simulation for optimal performance. The revolutionary Celestion Zephyr speaker, developed in collaboration with Celestion, emulates the iconic “Vintage 30” speaker sound at a fraction of the weight, using a traditional ferrite magnet.

Constructed with candlenut plywood for its strength, lightness, and acoustic properties, the St. James 50 EL34 Combo offers a robust yet lightweight design. The use of modern SMPS (Switched-Mode Power Supply) technology in the power transformers ensures universal voltage compatibility without compromising sound quality. The amp’s boutique look, complete with an illuminated logo, adds to its appeal.
