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 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.
