Series One 100

Series One 100 Overview

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 yet heard.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.

Further Info

  • ISF Control

    The ISF control works in conjunction with the Tone control. It allows you to choose the exact tone signature you prefer. Fully CCW is a more American characteristic with a tight bottom end and more aggressive middle, and fully CW is a British characteristic which is more ‘woody’ and less aggressive.

    DPR Control

    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.

    MIDI Switching

    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.

    Solid Construction

    All Series One 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.

    Speaker Emulated Output

    The Blackstar emulated output design is a new benchmark for pro direct recording. This no-compromise design makes it easy to get your tone to disk and tape. You can also use it to run a line out to a PA.

    Effects Loop

    The 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).
