Blackstar · amplifier
The Blackstar St. James 100H is the head-only version of the St. James 100 series, sharing the same 4-channel, 100-watt tube circuit and multiple onboard amp voicings as the combo version, paired separately with a compatible St. James cabinet rather than an integrated speaker. It's aimed at players wanting the St. James series' full tonal versatility with the flexibility to choose their own cabinet configuration.
