Behringer FM Filter Machine $$$$$

Brilliant little box from Behringer; I've bought an MFB Filterbox though and it's not getting enough use. Rather expensive to buy, that's why I'm selling it rather expen$$$$$ive. I;m not all that eager to let this one go, either. So that's why. I think it may be just about worth it, it's pretty great and great fun (I'd miss the fun part).
