Skeltron3030 Posted November 9, 2019 Share Posted November 9, 2019 Please provide a solution to this specific problem. Ive got loud humming on a 2018 gib lp tribute with humbuckers through my amp. It only goes away with pu selector in middle WITH one pu volume turned down. Any other configuration (both pu turned up, bridge only, neck only) introduces loud hum. Hum is not present when using other instruments with same amp and cable or when unplugged completely. This hum is NOT affected by touching strings.

Twang Gang Posted November 10, 2019 Share Posted November 10, 2019 Does it matter which pickup volume is turned down, or will the hum go away by turning either of them down while in the middle position? Sounds like some sort of grounding problem. Quote Link to comment Share on other sites More sharing options...
badbluesplayer Posted November 10, 2019 Share Posted November 10, 2019 Yeah - I'd guess ita a grounding issue, or maybe a bad connection in the wiring somewhere. Quote Link to comment Share on other sites More sharing options...
Skeltron3030 Posted November 10, 2019 Author Share Posted November 10, 2019 Hum goes away when either pup is turned down in middle position. Ill check out the grounding Quote Link to comment Share on other sites More sharing options...
Eracer_Team Posted November 11, 2019 Share Posted November 11, 2019 Part of the middle position is both volumes interact . Turn either one to zero produces zero sound. Just like being in either pickup and turning its volume to zero Quote Link to comment Share on other sites More sharing options...
