Blackstar Series One S1-104EL34 100w Head
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.
Speaker Emulated Output
All Series One 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 Series One 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.
