NAMM 2016: Stone Deaf unleashes "game-changing" SD valve amps with digital control

Introduction

NAMM 2016: As well as five tasty new effects pedals, Manchester's Stone Deaf has launched a range of equally desirable valve amps, the British-voiced SD series, which offer full digital control and the ability to save presets, plus full MIDI integration.

The range starts with the SD8 eight-watt lunchbox-proportioned head and progresses up to the SD50 50-watter – all amps are 240/120V switchable, while a range of lightweight poplar cabs are also available (below).

Stone Deaf SD8 Head

The baby of the range, the SD8 is a pure Class A compact head, outputting eight watts via 12AX7 and EL84 valves.

Two channels are available via a push-button on gain control, while treble, mid and bass are adjustable using the push-button tone knob.

Up to 16 presets can be stored across four banks, accessed using the push-button volume control or controlled via MIDI, while the amp's tonal range covers clean to crunch and drive.

With switchable wattage (30 watts Class A/B or eight watts Class A) via 12AX7s and EL84s, the SD30 offers increased versatility over its baby brother.

In addition, players can assign each of the amp's channels with solid-state and valve-rectified functions and power scaling, as well as fixed bias and cathode bias.
