Just bought this here on TB, in MINT condition. Velcro on bottom. $90 shipped The Mojo Hand Analogue Filter is based on the classic green DOD 440 Envelope Filter made popular by the members of Radiohead among others. It is NOT based on the incorrect schematics floating around the internet. The originals are getting hard to come by and the prices are going up accordingly. This one has added modern improvements like an LED and true bypass switching.
