Design Retro Works – Jerry Donahue Compressor


Brand New.

Based on classic design – this compressor provides the same top notch compression as the 4 knob version – but with a few tweaks courtesy of Mr Jerry Donahue – the twang master himself!

The JD-01 Compressor has been produced with the help of Jerry Donahue who has given his invaluable feedback in every aspect of the design, it is again based around the CA3080 Operational Transconductance Amplifier as used our other designs, but with the addition of a BLEND control. This models four external controls are Attack, Blend, Sustain and  Level (Compressor Output Only), the Input trim control available externally on our other models is still available but as an internal trim preset which can be adjusted on the PCB. So now more info about the BLEND part of the design, basically the original Input signal goes through a Split and Blend circuit allowing you to always have part of the input signal appearing at the output, Jerry specified this as he wanted to keep the dynamics of the original guitar signal, and be able to “mix” this into what appears at the output socket. With the blend control fully Anti-clockwise only the original guitar signal will appear at the output, fully clockwise only the compressed signal will appear at the output, this is useful for setting the parameters of the compressor, before you set a mix level, in between will give you a mix of both. The Level control on this unit only adjusts the compressed signal output so you can adjust the compressor to be higher in level than the original signal if required.

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

  • High quality double sided plated through PCB
  • Quality grade capacitors (Panasonic ECQ)
  • 1% metal film replace the original carbon 5% resistors
  • High Quality Switchcraft or Neutrik Input and Output Jack Sockets
  • True Bypass switching
  • Attack, Blend, Sustain and Level (Compressor) Controls
  • Internal preset for Input Trim Control adjustment
  • All transistors matched to within 0.1%
  • 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…   🙂 )
