Blackstar Series One 100 Watt EL34 Head
The Blackstar S1-104EL34 offers the tonal refinement previously found only in the very best boutique and vintage amps. Four EL34 power tubes form the backbone of this 100 Watt high-gain powerhouse, providing unbelievable dynamics and headroom. This innovative, all-tube head offers Blackstar's Dual Patent Design, plus many in-demand extras.

The S1-104EL34 offers Clean and Crunch channels, plus two high-gain overdrive channels (with high and low output damping) plus a second Overdrive Channel EQ (complete with independent ISF). The three-band EQ works with the Infinite Shape Feature (ISF) to provide infinite new tone-shaping control. The Master section provides Master Volume, Resonance, and Presence controls. Four EL34 power tubes deliver the best of British hi-gain tone. Dynamic Power Reduction (DPR) reduces the power up to 90% with no loss of tone, ideal for studios and smaller venue gigs. Professional touches include a Series Effects Loop, Emulated Speaker output, and MIDI switching.
