The Fat Bustard has all the features you'd expect from a high-end valve summing mixer: monitor outputs with level control and switching, precision ELMA switching on the main level which is also fadable, an 'attitude' control to increase harmonic distortion levels, and point-to-point handwiring throughout. Pan controls are also featured on 4 channels, and bespoke varislope top and bass lifts have been included for extra filtering.
