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,
