Distortion effect guitar pedal with genuine valve design that offers the ultimate in high voltage valve distortion flexibility and features two switchable channels for increased flexibility. Channel 1 has either Clean or Crunch modes so it can be used clean, as a boost or overdrive. Channel 2 gives distortion tones from super crunch right up to screaming lead. The unique, silent soft switching operation and a buffered bypass signal will transform a single channel vintage amp into a three channel tone machine. Patented ISF (Infinite Shape Feature) control works in conjunction with the Tone control: it allows user to choose the exact tone signature he prefers. 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. The pedal operates on a 300V DC anode supply voltage (High Tension voltage). This is the same used in traditional valve amplifier design and means the circuit has the headroom associated with a true valve design and will 'clean up' accordingly. The pedal will exhibit the compression and distortion characteristics associated with a true valve design. The Blackstar speaker emulated output design makes it easy to get the tone to disk and tape, and can be also used to run a line out to a PA. Dimensions: 160 x 119 x 80 mm. Weight: 1.2 kg.
