BLACKSTAR St. James 50 EL34 Tube Guitar Amplifier

Blackstar St. James 50 EL34 Tube Guitar Amplifier (Fawn)

Blackstar St. James 50 EL34 Combo is the lightest 50-watt tube amplifier in the world, weighing just 12.8 kg. Designed for guitarists seeking a classic, singing British tone, this Fawn finish model is powered by EL34 power tubes and combines traditional valve sound with cutting-edge recording technologies.

The amplifier features two channels: the first for a classic American-style clean sound, and the second for British Overdrive with a switchable Boost mode, providing additional gain for solo parts (+10dB). Thanks to a special cabinet made from Candlenut wood and a lightweight Celestion Zephyr speaker, this amplifier is incredibly convenient to transport.

One of the key features is the integrated reactive load and CabRig technology. This allows you to play and record silently (without sound from the speaker), sending the signal directly to a computer (USB) or mixing console (XLR) with top-class cabinet simulation. The power switch allows selection between 50W, 2W (for home use), and Sag (dynamic compression) modes.
