Super-HI 50

Custom Hiwatt Super-Hi 50W Head

Yes, it djents.

Classic Hiwatt at its core, the Super-Hi 50 is a hot-rodded, extreme hi-gain firebreather designed by heavy-metal Mike Fortin. Clarity, punch, string definition, and tight low-end are at the focus of this amp's design making it especially suited for drop tunings and extended-range instruments.


  • — Four cascading gain stages with an additional boost provided by the Custom Shop SUPER-HI Footswitch (included).
  • — Indepedent gain and master volume controls for both channels.
  • — Extreme high gain tones that don’t fall apart. Push this beast to your heart’s content, maintaining constant clarity, articulation, and responsiveness, especially in low tunings.
  • — Hiwatt’s premiere offering for low tunings, baritone, and extended-range instruments.
  • — Effects loop running after the high-gain preamp section for lush time-based or modulation effects.
  • — Based on the the original DR504 circuit, this amp loves gain Pedals in front, faithful to its pRedecessor.
