Blackstar Series One S1 100 Watt 2 Channel Head

These are as real as you can get - tube amps with no imitations!


Blackstar Series One S1 100 Watt 2 Channel Head

The latest addition to Blackstar, the Series One by Blackstar features a tube combo amplifier, two different heads and a straight and angled speaker cabinet. Each one is powered by tubes to give you the sound that your guitar was made for.

The specially designed DFR system means you can play at low volumes and still get the same tone and valve reliability.

What Blackstar say about the Series One Head

Built on the rock-solid foundation of the classic 100W EL34 power stage, this amplifier sets new standards for clean and crunch tones. Two channels and four footswitchable modes, complete with ISF, include the amazing Super Crunch for the biggest, crunchiest tones heard yet!

The DPR control allows power to be reduced to 10W for studio and small venue work, while a series effects loop and MIDI switching further expand the flexibility of this professionally specified amplifier.

Review from Music Radar - 4 1/2 out of 5 stars!

"One thing that's missing from so many multi-function amps these days is character. The Series 1 amps have tons of it, with all the flexibility you need. It's been a very long wait for these amps to arrive, but it's been worth every minute!"
