I recently installed a emg 85 in my dean vendetta and I'm getting some bad buzzing from it. The emg is the only pickup I have wired up, its just the 85 1 volume and 1 tone. I thought it was the ground wire. I tried grounding it to the casing of the tone pot like the instructions said but its still buzzing, even tried not grounding it. Could my output jack be screwed up bc its not like the jack that come with the emgs. Please help!
