100 Watt head - US metal voiced
The S1-104 is available in two output valve configurations delivering two distinctly different sonic signatures. The EL34 powered version, which is honed to deliver the ultimate in Brit influenced rock tones and this 6L6 version which has been voiced for a more aggressive US metal influenced sound. The amplifier comes with four footswitchable channels, two ISF controls and two sets of bass, mid and treble controls.
ISF Control - Everything from USA to UK
The patented ISF control works with the Bass, Middle and Treble controls to give you access to infinite new sound possibilities from the USA to the UK and everywhere in-between. This fully interactive control allows you to infinitely adjust the response of the tone control network between any of the traditional voicings. In this way you can design your own sound and truly find the sound in your head.
The DPR system allows you to vary the amplifier output down to 10% of its rated power without any loss in tone or valve reliability. Pure valve output distortion and compression at any volume - a dream come true.
The S1-100 offers the ability to control channel selection via MIDI Program Change messages and interfacing with most MIDI controllers is a straight forward process. The Series One can be placed in a MIDI chain allowing you to simultaneously select a channel on the amplifier and change the patch on a MIDI effects processor connected to the effects loop. There are 128 available Program Changes, giving you the possibility to access a vast number of tonal combinations.
Speaker Emulated Output
The S1-100 amplifiers have a state-of-the-art speaker emulator with balanced and unbalanced outputs via XLR and standard jack connectors respectively. The Blackstar speaker emulator is a complex multi-stage filter which takes the preamplifier signal and then introduces the important characteristics of a valve power amp, guitar loudspeaker and cabinet.
The S1-100 amplifiers have plated through double sided PCBs for the increased mechanical integrity this construction affords. Designed to last a lifetime, Series One cabinets have a 18mm finger-jointed birch ply cabinet and heavy gauge wiring. The chassis, for mechanical integrity, are seam welded 1.6mm steel.
Series Effects Loop
This amp features an effects loop to allow you to connect effects pedals or other professional equipment using the return and send connections. The Effects Loop Level switch sets the effects loop to either +4dBV/-10dBV, which enables you to use it with either professional equipment (+4dBV setting), or with guitar level effects such as effects pedals (-10dBV setting).
