I have been searching high and low for a blend pot for a jazz bass. 500k linear Dual-ganged Center detent Solid 1/4" shaft Solder lugs I know manufactures like Alpha make them, because I have seen them in other basses. But I cant seem to find them. I have found split-shaft versions on stewmac and guitarpartsresource.com, but no solid shafts. I have also looked on electronic component distributors like mouser.com, etc, but still no luck. Anybody know of a distributors that carry them?
