Analogue Systems FB3 Filter Bank
The FB3 from Analogue Systems is a CV controlled filter bank. It features 3 multi-mode filters chained together with final outputs for lowpass, bandpass, high pass, and notch filtering. The three filters cutoff frequencies can be set independently and also controlled from the master frequency knob. There is also an lfo which can control the master frequency or be patched out to control other modular equipment. The CV in will let you control the master frequency with external modulation sources.
This unit is used and it is sold as-is.
