Hi list, While digging in my parts drawers I found A vintage Oberheim FS-7 Sustain Footswitch in very good shape. http://www.arcenson.com/public/Oberheim_FS-7_footswitch.jpg I think it was to be used with OB-8 and Matrix-12. It's a normally open momentary switch. I'd be willing to sell it for $40 + s/h. Sorry for interrupting. JP
