The Blackstar STJ50EL34H is a specific model of guitar amplifier head within the Blackstar St. James series. It is a 50-watt, all-tube head that is distinguished by the “EL34H” designation, indicating it uses EL34 power tubes. This model is designed to deliver classic British-style tones, with chimey cleans and a vintage-leaning “British crunch” on its gain channel.A key feature of the entire St. James series is its focus on being the “lightest 50-watt valve amps on earth.” This is achieved through the use of lightweight candlenut plywood and a Switched-Mode Power Supply (SMPS) for the high-voltage circuitry, which drastically reduces the weight compared to traditional amp designs.
