BLACKSTAR St. James 50 EL34 212 Tube Amplifier

Blackstar St. James 50 EL34 212 Tube Amplifier

Blackstar St. James 50 EL34 212 is a revolutionary tube amplifier designed for guitarists who want true 50-watt tube tone without the back-breaking weight. Thanks to its specially designed candlenut plywood cabinet and lightweight "Celestion Zephyr" speakers, this 2x12 combo weighs only 16.8 kg, which is almost half the weight of traditional amplifiers of this type.

This model is equipped with 2 x EL34 power tubes, delivering classic, warm British crunch and singing tone. The amplifier has two channels: Channel I offers an American-style clean sound, while Channel II provides classic British Overdrive with a switchable "Boost" mode (+10dB) to increase the signal for solo parts.

One of its most distinctive features is the integrated Reactive Load and CabRig technology. This allows the amplifier to be used silently (without sound from the speaker) and record studio-quality tone directly to a computer via USB or XLR output, using advanced cabinet simulations. The Power Reduction switch allows selection between 50W (full power), 2W (for quiet playing), and "Sag" (compressed, vintage feel) modes.
