Model 77 High Voltage Tube Distortion / Modulation / Preamp with Germanium + Gallium Fuzz



Remember the days when ideas were “better said” when stated in a romantic language of the continent? De Luxe, Coupe De Ville, Riviera, hell even Chevrolet referred to the ideals of a cosmopolitan culture rather than the closed-minded ways of the provinçial hayseed armed with pitchforks or worse.

With an unkempt (but sincere) nod to what little WAS good in the old days we country luddites seek to deliver the pure, the simple and the dangerous sound borne exclusively of High Voltage Tubes. The Model 77 HT (“Haute Tension”) handily shames the voltage-starved, hard soldered prêt-à-portere sold by Mc-Corporate wherein the chinese glass-work serves little purpose beyond the role of glowing eye candy to distract from the sorry digital corn syrup sound of “100 half-assed-half-stack choices on a chip-pedal”.

The Model 77 features:

  • Slovakian Twin-Triode High-Gain Tube
  • Traditional High-Voltage Operation
  • Bypassable Germanium & Gallium Rectifier Sets
  • “Honest to desert-diety” Natural All-Tube Distortion
  • Excellent Harmonic Modulation Control
  • Adjustable Effect Gating 
  • Plug & Play Modification to ECC81 & ECC82
  • Hand Made in USA

Model 77 excels with Guitars, bellows with Bass & sings like an electric chorus with Keys. Its array of controls allows warm tube pre-amplification, lush tube distortion, bypassable rectifiers of both germanium fuzz + gallium crunch. Fine tuning allows the effektor’s unique gating function so as not to scream through negative space in your maestro’s repertoire.
