AVP Polyrhythm Duo Filter

For Sale – AVP Polyrhythm Duo Filter

I’m selling my AVP Polyrhythm Duo Filter on Reverb. It’s in great condition and the only reason I’m selling it is because I started using a Waldorf 2-Pole (few more options). This is loud and dirty though and has some unique characteristics to it, especially the LFO.

From AVP
