The Little Bustard is Thermionic Culture's second valve summing mixer and is designed to be used either as a standalone mixer or as a complement to Thermionic's Fat Bustard summing mixer.

Features include 16 input channels arranged as 6x stereo pairs with fixed gain at unity level and on/off switches, 4x mono inputs with mute switches and switchable pan pots (disabling the pan pot will add an extra 6dB of gain). The master output section has independent left & right 31 position output indented pots with a gain range from –17db to +2db. The valve stages use a pair of ECC83/12AX7 on the gain stage, and a pair of PC86’s for the output stage. To create a monster-summing mixer, The Little Bustard’s outputs can be plugged into the Fat Bustard’s AUX inputs for a total of 28 channels.
