Thermionic Culture Fat Bustard Summing Valve Mixer

The Thermionic Culture Fat Bustard is a summing valve mixer with a total of 12 inputs and unique features.

The inputs on the Thermionic Culture Fat Bustard are arranged as follows: 4x stereo pairs, 4x mono with pan controls, and all the channels have toggle mute switches. The simple but amazing Bass and Treble EQ has 0.5dB stepped Lift controls while there are 6 way stepped Bass and Treble Cut controls.

The Thermionic Culture Fat Bustard also features a really sweet and effective stereo width control. Four valves are used on the master buss, a pair of 5965 double triodes, the first half of which is pre-amp/eq , the second half is gain makeup in conjunction with the dedicated ‘Attitude’ feedback control which determines the amount of THD. The Attitude control can yield a clean signal or add gain and some “valvy” 2nd harmonic distortion. The other pair of valves is the larger 6SN7 double triode connected in parallel to give massive headroom, approaching +30 dBm.
