Blackstar S150 Head

By switching both preamplifier and power amplifier parameters, the Series One 50W delivers both Class A style tones with a bell-like ring and classic push-pull crunch depending on the mode selected.

The Patented ISF control removes the limitations of traditional designs allowing you to tune the tone to exactly the sound you are looking for. DPR can reduce the power down to 5W, whilst MIDI switching and a series effects loop makes this the ultimate pro head.
