Gotharman's Tubaz tube filter board for Anamono X and Xmini

Tube filter with characteristic fat, warm and distorted tube filter sound. Lowpass, bandpass and highpass modes are available. Output 1 is switchable between lowpass and bandpass modes, output 2 is always in highpass mode. The Out1/2 control mixes between LPF/BPF and HPF. It also has negative analog feedback, that can make it sound thinner.
