Setting new standards for tube tone and flexibility!

The S1-104EL34 guitar amp head 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 Infinite Shape Feature). 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.
