Blackstar ST. James 100 Head
Blackstar · amplifier
The Blackstar St. James 100 is a two-channel EL34-powered tube guitar amplifier head combining American-voiced clean tones with British-voiced overdrive, designed as a lightweight handcrafted valve head with features including a sag control, effects loop, and reverb. Channel 1 delivers big, open clean tone with clear black-panel-influenced headroom; Channel 2 produces British crunch that leans toward Vox chime and articulation rather than Marshall darkness, making it unsuitable for saturated high gain but excellent for chimey, cutting rock and blues. Reviewers describe the EL34 version as combining world-class British crunch with US-sounding clean tones in a design notably lighter than comparable valve heads.
