The St. James Series: the 50W all-tube amp designed for mobility (without compromise)
With the St. James range, Blackstar tackles a "real" guitarist problem: achieving an organic 50W tube tone without ending up with a combo that's hard to transport. The St. James 50 6L6 212 follows this philosophy to the letter, with optimized construction (candlenut plywood) and specific work on the speakers. The result: a credible stage amp, but also a modern studio tool thanks to an integrated direct recording section.
Who is this 2 x 12-inch combo best suited for, and in what contexts?
The Blackstar St. James 50 6L6 212 is aimed at guitarists who want a true tube amp capable of covering a wide range of situations: rehearsals, studio, and stage. The 50W provides enough headroom to play with a drummer without strain, while the 2W and SAG modes make the amp more usable at reasonable volumes, especially for working on tube feel and natural compression.
In terms of styles, the 6L6 base delivers a wide and bright clean perfect for blues, country, funk, pop, and rock. The overdrive channel, more aggressive, clearly targets modern rock and heavier genres (hard rock, modern metal), while remaining precise for palm-muted rhythms and leads that need to "cut" in the mix.

Questions frequently asked
Can the Blackstar ST James 50 6L6 212 be recorded directly via USB or XLR?
The built-in reactive loadbox allows capturing a post-power amp signal. The CabRig DSP adds speaker cabinet and microphone simulation through the CabRig XLR output or USB audio. This setup takes advantage of the tube power stage behavior without requiring microphone re-recording.
Is the St. James 50 6L6 212 usable at low volume?
The power reduction offers 50 W, 2 W, and SAG modes. The 2 W mode lets the amp break up earlier, while the SAG mode provides smoother compression.
What tone do the 6L6 tubes of this combo provide?
With 2 x 6L6 and 2 x ECC83 tubes, the amplification delivers a broad clean sound, open highs, and tight bass. The 50 W power retains definition when played aggressively and offers enough headroom for playing with a drummer.
What is the weight of the Blackstar St. James 50 6L6 212 combo?
Weighing 16.8 kg and measuring 685 x 535 x 260 mm, it is easy to transport for a 2 x 12-inch combo.
Does the effects loop accept delay and modulation pedals?
A series effects loop with level selector is integrated to connect modulation, delay, or reverb pedals. The 2-way FS-20 footswitch is included to control the associated functions.
