http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1741243250 Nice 3/4" black skirted knobs with set screw for 1/4" shaft. Dutch auction for 100/lot, he's got 1500 of these. Looks like the kind sold at Radio Shack (probably is Radio Shack). I used these on my original synth. They're pretty nice. -- Scott Bernardi sbernardi at attbi.com
