About Thermionic Culture Ltd 12 Channel Summing Mixer

Mixer (special equalisation for the mix,stereo width, bass to centre) 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 6072A double triode input valves in place of 5965s.

Both Fat Bustards have exactly the same 14 inputs, and same controls. The black more Aggressive Fat Bustard continues to be made, so the user has a choice until all the Green ones have been sold.
