So i got a Seymour Duncan JB humbucker for my strat and i wanted to wire it up without the tone pots because im completely new to witing and i also want to have a more “full” tone coming from my guitar. But when i wired it up the way the diagram said, i would only put one string on each time and plug the guitar into my amp but when i did that there wasnt any pickup from the strings but there was a loud buzzing sound (kinda like feedback). Can anyone help me with this? Also i can only get a faint sound from the string when i disconnwct tge ground wire fromthe bridge connection on the back of the guitar. Any help?
