Haz MutronIII+ envelope filter for sale. I love this pedal, especially the down envelope setting and bass response, I just don't get to play the funk much these days. Settings for both bass and guitar if you're versatile like that. Fair amount of small cosmetic dings from being kept in my gig tool box til I realized that wasn't a good idea and made myself a pedal board. Overall decent condition and not actually used very much.
