sk8 Posted April 16, 2008 Share Posted April 16, 2008 I've had the stock EMG Select pups in my hohner replaced with wizard 84's. Great pups but i've got a problem - buzzing background noise until i touch the strings or bridge. I've gone through all the usual with my guitar tech, checked joints, earthing points, shielded the cavity but its still there. Andy at wizard has said that he will shield them. My guitar tech said that all thats left is the shield the pups and wires. I know the 84's are more than double the output of my old ones. Anyone got any ideas or should i just get on with getting the pups shielded? Thanks in advance Quote Link to comment Share on other sites More sharing options...

Some have Wizards installed, some don't. To be honest, I just make sure I'm touching the strings all the time. I do it without thinking about it now. If it hummed while you were touching the strings... *that's* a problem. Quote Link to comment Share on other sites More sharing options...
mr pablo Posted April 16, 2008 Share Posted April 16, 2008 you can use copper foil to shield the control/pup cavity, its fairly cheap from axesrus/ebay/wdmusic etc and relatively easy to use as its sticky backed there is a big post on talkbass about it [url="http://www.talkbass.com/forum/showthread.php?t=159191"]Here[/url] Quote Link to comment Share on other sites More sharing options...
thinman Posted April 16, 2008 Share Posted April 16, 2008 I've got 84s on my MIM Jazz and don't suffer any noise problems at all. Is the hum as bad when both pickups are switched in / turned up? I think the pickups are supposed to be wired in opposite phase to each other so that hum is cancelled out which is why when one or the other is switched out or turned down the hum increases. Have yours been put in in-phase with each other perhaps? Quote Link to comment Share on other sites More sharing options...
sk8 Posted April 17, 2008 Author Share Posted April 17, 2008 (edited) Thanks for the replies what is odd is when i got it back after the pup change it was fine but i got it out for a practice a couple of days later and got the hum. Its just annoying. i think i am just going to have to get the pups and cables shielded. Edited April 17, 2008 by sk8 Quote Link to comment Share on other sites More sharing options...
GreeneKing Posted April 17, 2008 Share Posted April 17, 2008 Is it possible that the bridge earth has come adrift somewhere? Maybe put a wire from earth on a pot to the bridge and see if the hum goes? Peter Quote Link to comment Share on other sites More sharing options...
sk8 Posted April 17, 2008 Author Share Posted April 17, 2008 will try that tonight Quote Link to comment Share on other sites More sharing options...
sk8 Posted April 23, 2008 Author Share Posted April 23, 2008 well i removed the bridge and moved the earthwire put it back together and the noise has gone! Still got a very low level single coil hum but as Andy at wizard said "thats character"! Quote Link to comment Share on other sites More sharing options...
Old Horse Murphy Posted April 23, 2008 Share Posted April 23, 2008 I get really bad pickup buzz at our rehearsal stusios because they've fitted cheap dimmer switches in all the rooms!! No idea why you'd need a dimmer switch in a small room with 5 sweaty men, but then I was brought up proper like.... Quote Link to comment Share on other sites More sharing options...
sk8 Posted April 23, 2008 Author Share Posted April 23, 2008 its because of the sweaty men - so you can dim the lights and not see them! Quote Link to comment Share on other sites More sharing options...
