If you feel like mixing “in the box” is leaving your mixes sounding just a little bit flat, you need to consider moving up to the punch, warmth, and definition of an all-tube analog summing mixer. The Fat Bustard from the fertile minds at Thermionic Culture lets you avoid the bit-dropping, sound-muddling audio compromises involved in digital summing while letting you add great-sounding tube EQ, tweak the stereo spread and lay on just a little bit (or a whole lot) of classic tube drive to your mix. Analog summing is the secret weapon of many top mix engineers, and adding it to your arsenal will open up a new sonic frontier.

The commitment of Thermionic Culture’s founder, Vic Keary, to high-quality tube audio gear dates back to the first studio he built in the 1950’s, and his company has taken the best of what tubes have to offer, updating the circuits for the low-noise and distortion levels required for modern recording. Solid-state components are confined to power supplies so that the audio path is pure tube musicality.

Think and mix outside the box with a Fat Bustard

  • 14-Input passive-input all-tube summing mixer
  • Four stereo inputs, four mono inputs with defeatable pan pots, and a hard-panned stereo auxiliary input
  • Stereo two-band EQ and stereo width controls
  • 6-position “Attitude” switch adds varying amount of tube drive
