Add a footswitchable boost and lush, long-decay spring reverb and you an extremely versatile, unique, and formidable full-range amplifier.


  • — Independent Hi and Low inputs. Versatile and intuitive, perfect for bringing life out of dark pickups or taming shrill high end in bright pickups.
  • — Push/Pull Gain potentiometer providing extra preamp gain at a touch.
  • — Volume for any gig — Switchable wattage allows switching from 40W down to 20W for smaller venues and practice spaces. Furthermore, this gives the option of more clean Headroom in the 40W ’Studio’ mode, or natural tube breakup in the 20W ’Stage’ mode.
  • — A fantastic Pedal platform, with natural tube saturation and True-Spring Reverb on tap when you have to leave your board behind.
