I know i have seen a link here to a site that sell pre-wired preamp kits with pots but i can't seem to find it. Any help would be great. Also, if you know any other companys that sell prewired preamp kits other than the manufacturers (if they even do it) please post. I'm looking to soup up my old jackson to see what it can really sound like. And the less soldering i have to do, the better off my bass will be.
