When a randomized voltage controlled filter shows up at the local shop, you have to try it out. Does it work on bass? Yes. Of course. Is it the sound you want? Probably not, but I love it!

The Acetylene Nirvana is no longer in production and the company -Lone Wolf Audio- is no longer in business, but maybe you can find one of these out there. It’s a clone of the Oberheim VCF-200. Maybe that helps?
