mr.chEn Posted February 17, 2009 Author Share Posted February 17, 2009 after reading some older posts on the forums it seems to be a grounding issue, however that doesnt fix the problem that there is still a trace amount of hum even when the volume knobs are rolled all the way off.. either way, how do I fix the grounding issues?

rmngretsch14 Posted February 17, 2009 Share Posted February 17, 2009 Grounding issues are difficult, because you don't really know where the ground fault is, so basically check every connection, my guess is its at the switch or the output jack. It's even somewhat possible it's in the pickups themselves, in any event its going to be a pain and unless you like the messing around with the wiring in a 2 grand+ guitar I'd say pass it off to a tech Link to comment Share on other sites More sharing options...
rocketman Posted February 17, 2009 Share Posted February 17, 2009 There might be some interference around. There is no such thing as a perfect "humbucker." It may be due to a number of factors in and around your house. Try plugging it in at different locations around the house or use another amp if you can. Did you just notice it or has it always been there? It may be an electrical issue (impedance regulator on the fritz or something). Are you next to a computer monitor, fluorescent lights, metal poles (that used to be a killer for us when practicing in our basement), etc.? Anyhow, start off being trying to get into an clean (interference free) zone. Link to comment Share on other sites More sharing options...

Environment may not be an issue. Did you replace the chords? Did you use a different amp? Does it get worse when you get closer to your amp? Are you using any pedals? Try to isolate where the problem is first and then work from there. Link to comment Share on other sites More sharing options...

For about $40-$50 I'd have a tech look at it. Unless you really know what you are doing, let an expert fix it for you. I've fixed a lot of problems with my Sonex over the years but I'm not comfortable doing that level of work on my Les Pauls yet. Better to be safe with a tech than sorry on a fine instrument like that... Link to comment Share on other sites More sharing options...
elessar820 Posted February 17, 2009 Share Posted February 17, 2009 I've had this problem with both my Les Paul BFG and Flying V. I shielded the cavities with aluminum tape and it made a huge improvement. You can use copper tape or shielding paint, which may be better, but aluminum tape is all that I had available. If you do shield the cavities, make sure to shield the cover and ground the shielding to the back of a pot. Since you can't solder aluminum, I have the ground attached to the pot and between the cavities lip and the shielded cover. Link to comment Share on other sites More sharing options...
rockstar232007 Posted February 18, 2009 Share Posted February 18, 2009 I had this problem with my EPI LP, it turned out to be because of the pickups themselves not being potted (in wax) properly, so I took the covers off, re-potted them, put them back in, and PRESTO! No more hum! Link to comment Share on other sites More sharing options...
