Dirty Doper

The Dirty Doper is currently in redevelopment – 18 May, 2017. Please note following descriptions apply only to the first generation design, and while most (if not all) features and character will be carried into the Mk. II it remains in redesign so nothing is guaranteed.

The RMA Dirty Doper is the result of a somewhat over-reaching spasm of audio exuberance. The signal journey begins at a somewhat reactive initial gain section it is then chopped into two and thrown headlong into traffic.

Sorry about that. I just tried to describe what is going in via text and experienced brain freeze, so having deleted that mess here’s a run down of features instead:

  • Monophonic pedal, with two inputs (join!) and two outputs (split!) to facilitate sub feedback loops or other utilitarian needs
  • Gain control
  • Parallel fuzz circuits
  • Switchable low frequency boost
  • Blend between paths (of the parallel fuzz mentioned above)
  • Destabilization of summing section with selectable contours
  • Polarity selection of one fuzz in relation to the other
  • Native feedback mode that functions differently than an output to input cable AND a “let’s get rid of the highs instead” smooth sailing mode (for when tinnitus stops by for a while) on the same three position switch. The other position is normal, whatever that means.
  • Control voltage inlet that will mirror your CV reference at the power rail, meaning, externally controlled voltage starve – this is a primitive function and the lower range of CV generally does not exhibit enough voltage to wake the circuit up.
  • Output volume

Until I cut a satisfactory demonstrator myself, these 3rd party videos cover a lot of ground:
