Clyde Posted November 28, 2004 Report Share Posted November 28, 2004 (edited) Ive just finished up my guitar, Mightymight Humbuckers (Motherbuckers) There wired up fine, make all the right noise, apart from one, a constant buzz, which goes away when i touch any grounded metal component Ive spent ages checking the grounding makeing sure they all ground and they do, (I soldered all the grounds to a Tone pot, then grounded the pot) It all earths and ive checked it by using a circuit tester from the tone pot, to the other end of the cable earth Seems to me that its not grounding right, but grounds perfectly fine through me when i touch it Defiantly isnt the amp, ive tested it on 4 differnt amps, the Jack wireing is the correct way round also Ive been reading this up on the internet for an age and to no result too, i really want to get using my new guitar for my GCSE music work Please help Edited November 28, 2004 by Clyde Quote Link to comment Share on other sites More sharing options...
Southpa Posted November 28, 2004 Report Share Posted November 28, 2004 (edited) You haven't mentioned grounding the bridge. Since its an LP I'm assuming you have a TOM style bridge installed. You will have to devise a way to get a wire in contact with one of the bridge mounting studs and then hook it up to your central grounding point. The last 2 guitars I built both involved TOM bridges but I installed pickguards that extended right to the bridge. All I had to do was pull a bridge mounting stud, insert wire, replace stud and lay the wire into a slot cut into the body UNDER the pickguard. From there I threaded to wire through the same hole used by the pickup wires to my central grounding hub, the volume pot.

MikeB Posted November 28, 2004 Report Share Posted November 28, 2004 hey!!! same pickups as me! they are AWESOME! (im gonna use these instead of EMG's, cos i think they are wild better!!) anyhow i had the same prob. then i grounded the bridge and shielded everything well, they are fantastically quiet now! i highly reccommend shielding all the cavaties, and the back plate, earth everything and they will rock! cya later!

Clyde Posted November 28, 2004 Author Report Share Posted November 28, 2004 The bridge is indeed not grounded, will it help if it is?, i personally cannot see how Alittle explination? i tryed sheilding the Control Cavity, didnt change much (Btw, the pickups are sweet, nice and meaty i say!)

Clyde Posted November 28, 2004 Author Report Share Posted November 28, 2004 (edited) Ahh i see, it works by when i touch the strings it grounds though me as well?, is there anyway i can get it to be silent with out touching the strings?

feylya Posted November 28, 2004 Report Share Posted November 28, 2004 Yes. This may be completely wrong so take it with a lump of salt but by grounding, the buzz from the pickups goes through the strings and cancels it out... Like I said, that may be complete BS but hey, it works! Quote Link to comment Share on other sites More sharing options...
Clyde Posted November 29, 2004 Author Report Share Posted November 29, 2004 Well, Grounding the bridge helped alittle, Alought it pops when i touch the strings (No Shock), Which gets rather annoying Quote Link to comment Share on other sites More sharing options...
LukeR Posted November 30, 2004 Report Share Posted November 30, 2004 How much 'pop'? Just a question, how much reverb are you using? If it is what I am imagining, you should turn off the reverb and see if its still happening. Just a theory, Luke Quote Link to comment Share on other sites More sharing options...
Clyde Posted November 30, 2004 Author Report Share Posted November 30, 2004 Same pop as when i touch any metal component of the guitar thats earthed, its defiantly an electrical pop, not using any reverb at all Quote Link to comment Share on other sites More sharing options...
VanKirk Posted November 30, 2004 Report Share Posted November 30, 2004 After you shield your guitar you can isolate the bridge & strings from AC pop by using a 0.1uf 450V (or so) capacitor between your cavity shielding and string ground. Does your guitar have metal knobs? If metal knobs are used on the pots, the pots and the pup switch won't be grounded. Quote Link to comment Share on other sites More sharing options...
Clyde Posted November 30, 2004 Author Report Share Posted November 30, 2004 I dont have metal knobs, one day i might (if they ever arrive) do you suggest grounding the Pot casing?, Also my Pup selector switch Is grounded Ill work on getting a 0.1uF 450v Cap from my electronics teacher Quote Link to comment Share on other sites More sharing options...
feylya Posted November 30, 2004 Report Share Posted November 30, 2004 Always ground the pot casing and only have one ground wire coming in. Solder the ground from the jack and ground from the bridge to the same pot then take a wire from that pot to the other pots. Quote Link to comment Share on other sites More sharing options...
Daniel Sorbera Posted November 30, 2004 Report Share Posted November 30, 2004 (edited) ok ok I know this is for single coils, but I did it to my humbucker equpied guitar and it silenced it... Just read through it and once you get the general idea DO IT. Basicly what you want to do is tie all the grounds together at one point than wrap that in rubber tape and run ONE wire to the ground... well you get it just read the thing Edited November 30, 2004 by Godin SD Quote Link to comment Share on other sites More sharing options...
MikeB Posted November 30, 2004 Report Share Posted November 30, 2004 feylya, by connecting the bridge to ground you achieve nothing, its when you attach yourself to the ground. your body acts as a massive antenna, picking up all the noise of the day! when you earth the bridge, you are virtually always touching the therings or bridge, this connects you to ground, shorts all the inteference you would transmit into the pickups to the ground, therefore reducing noice. im sure if this doesnt make enough sense LK or ansil will help.
