Blackstar St. James 100 Combo

The Blackstar St. James 100 Combo is a 100-watt all-tube guitar combo amplifier that redefines the modern valve amplifier by combining authentic tube tone with cutting-edge recording technology, exceptional portability and professional stage performance. Despite its powerful 2×12-inch speaker configuration, it weighs just 16.8 kg, making it one of the lightest all-tube 100-watt combos available.

Powered by 3 × ECC83 preamp valves, 2 × 6L6 and 2 × EL34 power valves, the amplifier allows players to switch between valve types in 50-watt mode or combine both for a unique 100-watt hybrid valve experience. This delivers the sparkling dynamics of classic American amplifiers together with the punch and character of legendary British valve designs.

Four fully footswitchable channels cover everything from pristine cleans to modern high-gain tones. The Crunch channel features a dedicated Boost, while the OD2 channel includes a Tight Voice mode for tighter bass response and enhanced articulation. Additional professional features include continuously variable power scaling down to 5%, CabRig™ Advanced DSP, USB audio, balanced XLR D.I. output, MIDI compatibility, and a supplied 6-way footcontroller.
