The HT-DUAL offers the ultimate in high voltage valve distortion 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 switching operation will transform a single channel vintage amp into a three channel tone machine. The ISF control takes you from British Valve to Modern American and anywhere in between and the no compromise speaker emulated output lets you get it all down to tape or disk.
