Frostwave Funk-A-Duck Envelope Filter #18. Extremely funky! Very nice if you want an extremely adjustable envelope filter. The adjustability makes it nice if you want to not only run a bass signal into it, but any other instrument like synth, vocals, or keyboard.
Very hard to find but well worth the price...this filter replaced my Q Tron and sounds better to me than my HAZ Mutron III and my Maxon AF-9.
The Funk-A-Duck is in fantastic condition and comes complete with power adaptor and original box.
PRICE: $225 INCLUDING SHIPPING in the con USA.
