Thermionic Culture Fat Bustard Limited Edition (Green) Unbalanced/Balanced


SKU: TCFBLEG Categories: ,


This Special Thermionic Culture Fat Bustard Limited Edition (Green) is introduced for those purists who want the facilities of the Fat Bustard mkII summing mixer but a little less colourisation – and even lower distortion and noise…..though not as much max “Attitude”.

The top response now extends to 50+ kHz with consequently less phase shift. It uses 12AY7 double triode input valves in place of 5965s.

Both Fat Bustard mkii and the Limited Edition have exactly the same 14 inputs, and same controls.

The black coloured more aggressive sounding Fat Bustard mkii continues to be made, so the end user has a choice until all the Green ones have been sold.

Both are the same price.


The main features of the Thermionic Culture Fat Bustard Limited Edition (Green) include:


  • All valve 14 input passive summing mixer with many Limited Edition extras
  • Pan controls on 4 channels with centre detents.
  • Unique Varislope Top and Bass lifts plus filters.
  • ‘Attitude’ control to add harmonics.
  • Stereo width controls / Bass to centre and mono.
  • Precision ELMA switch to control main level (fadeable).
  • Monitor outputs with level control and switching.
  • Hand wired with point to point wiring throughout.
  • Exceptional sound quality – very low distortion except when required
  • Massive ‘headroom’.
  • Frequency response extends from below audio range to well above.
  • Hand Made in UK.
