leadgit1 Posted January 20, 2010 Share Posted January 20, 2010 Hi guys. I have an update on the Epi Les Paul Standard OBL I recently obtained. I have been inside guitars for 35+years and have come across a unique situation with this 97 OBL. Has anyone ever seen a neck pickup wired to the tone pot instead of the volume pot. Is there something very basic I am missing here. I spoke with the origional owner who bought it new in 97 and he says he never took the cover plate off. I was curiouse about the extremely low output of the neck pup and that is what I found when I opened her up. 97 Epi Sam Ash Les Paul Standard OBL edition bone stock 98 Strat with EMG DG 20 compliment and a solid maple Cort neck. 01 Ibanez S470 minus the mid,single coil pup. 02 PRS Santana SE w/added 2nd volume control. 89 Cort Strat model w/maple neck. 2004 Epi Duke University commemoritive edition heavily upgraded and modified. 2006 First Act Garage Master "Volkswagon edition" upgraded for playability. Vintage Silvertone Stratatone w/Filtertrons, Tune-o-matic bridge, Mighty Mite tuners. Link to comment Share on other sites More sharing options...

Normally the p_up is wired to a volume that is set up as a potentiometer and the tone pot is set up as a low pass filter with the cap between the volume pot and ground. The rolloff curve is determined by the tone pot resistive value. More series resistance between the p_up and the cap in the circuit, the more treble available at the jack. Although wiring a pup to the tone pot is possible, the configuration needs to be a bit different and you don't have as much control on the volume as you rolloff the the tone pot combining the two. I can't see it being factory wired this way..somebody somewhere had to alter the wiring, if it is indeed wired up the way you say it is. Link to comment Share on other sites More sharing options...
