STU-SBL Posted December 23, 2010 Share Posted December 23, 2010 (edited) I assume these are single coils? Are the pole pieces shielded, i.e. copper screened and grounded to earth on the jack socket, pot or other ground point? [b]My interpretation of your problem:[/b] From your description, by turning the treble all the way up you are magnifying the sound. Alternatively, by turning the bass up you are diminishing the sound... although the same interference will be present. By touching the strings, bridge, pole pieces etc you are soaking some of the interference (sound you can hear) caused by the magnetic field of the pickups. Your bridge will be earthed (assuming this has been done correctly) I may be wrong though A little more information may help.

BOD2 Posted December 24, 2010 Share Posted December 24, 2010 Have you checked through the "sticky" thread ? [url="http://basschat.co.uk/index.php?showtopic=194"]Grounding Issues[/url] Most of the common causes/cures are mentioned there. Quote Link to comment Share on other sites More sharing options...
Ou7shined Posted December 24, 2010 Share Posted December 24, 2010 The sticky is probably best. It's real hard to offer help when the OP is sure they've checked everything. Pics is the way ahead to spot something that may have been overlooked with out going through every single possibility over the net. Quote Link to comment Share on other sites More sharing options...
