Does anybody have an easy to read wiring diagram of a Ric 4003 with the vintage/modern switch? When I solo the bridge pickup, it sounds very weak and thin. In comparison, the neck pickup is very full sounding. The vintage/modern switch makes no difference to the tone at all, like it's not even functioning. I'm wondering if someone modded it back to original specs, or if there is something wrong. I found the Ric schematic on their site, but I'm not very good at reading them and all of the diagrams at Joey's have been taken down.
