About the Blackstar Series One 100 amplifier:

This amplifier is built on the rock-solid foundation of the classic 100W EL34 power stage. As a result, it sets new standards for clean and crunch tones. Two channels and four foot-switchable modes, complete with ISF, include the amazing Super Crunch for the crunchiest tones yet. The DPR control allows power to be reduced to 10W for studio and small venue work. So this is great if you want the tone but without the high volumes. A series effects loop and MIDI switching are also useful features on this amp.


  • 100W Watt head with built-in power reduction.
  • Choice of 4 x EL34 or 4 x 6L6GC power valves/tubes.
  • Clean channel with Warm (Plexi) and Bright (Class A) type modes.
