Design Retro Works – Si Fuzz Ace


Brand New.

Distinctly different to the smooth fuzz of the Ge pedals, this is more angular and abrasive.

You can still tell it’s “your guitar” through it though it doesn’t fall into the trap of making all guitars sound the same!

The DRW Si Fuzz Ace is again based around the original Arbiter “Fuzz Face” circuitry with a few tweaks of our own, a classic, using again a great set of NPN Silicon transistors, which, as far a we know are previously unused in this design. We have modified for True bypass and LED operation and have used quality components throughout. This model has a great range of sounds from a simple Fuzz to full intensity and sustain.

Only the best components are used throughout the manufacture of all our units:

  • High quality double sided plated through PCB
  • 1% metal film replace the original carbon 5% resistors
  • Quality grade capacitors (Panasonic ECQ)
  • High Quality Switchcraft or Neutrik Input and Output Jack Sockets
  • True Bypass switching
  • Fuzz and Level Controls
  • Internal Preset adjustment of transistor bias voltage
  • Aluminium Knobs
  • Blue LED
  • High Quality 3PDT switch
  • Standard 9v negative centre DC power socket

DRW has been founded in the heart of Lancashire by an engineer who has spent the best part of twenty years working for Neve, AMS and Calrec.  As such he has a high class pedigree in analogue audio, and has modified certain “classic” pedals to meet his demands.  Great sound, low noise (background noise that is…   🙂 )
