I'm a little confused with the parallel/series configuration for a Jazz bass. I've seen a bunch of different schematics, but seems as if some people are using a push/pull pot and some a dpdt switch, some both? Totally confused. I'd like the push/pull put configuration better, seems as if it would be a cleaner setup (no extra hole for a switch). Does anyone have a picture of their cavity control with either one of these configurations? Which push/pull pot are you guys using? One seller on eBay sells something very interesting. Is this a good configuration? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7394906569&rd=1&sspagename=STRK%3AMEWA%3AIT&rd=1 Thanks for the help.
