I have a Squier VM p bass, which has shielding paint in it and the standrd "duncan designed" pickups. It buzzes quite badly, but calms down a fair bit (but not totally) when I touch the strings. Tone up makes it worse. Is it likely theres a poor earth connection to the bridge ?
second question, doesn anyone know if shielding paint is superior to copper tape with conductive glue ? I have some spare tape, and I'm tempted to add it but not if there is no gain
thanks.
EDIT - I solved my issues. I put extra shielding in, and tucked a little foil up so it reached the foil on the back of the scratchplate.I noticed that resistance from the bridge to the jack (0.50 ohms) was much higher than from the pots (0.009 ohms).
Taking the bridge off I noticed that although the earth wire was in place, the exposed wire was twisted and quite slender so contact with the rough underside of the bridge was less than ideal. I pulled it through a little and put a piece of sticky copper foil over it to a ) stick it down and b ) widen the area of contact. This reduced the resistance from the now-refitted bridge to the jack socket to just 0.008 ohms. Bass now very quiet.
