BTW is there somekinda fix for this

A cover or baseplate made of steel will affect the pickup's response noticeably less than one of brass or copper, which are more electrically conductive. More conductive = less resistance = larger induced eddy currents = larger opposing magnetic field. Nonconductors such as typical plastics effectively have infinite resistance and don't carry eddy currents, so there's no countering magnetic field produced. While true, the major effect from conductive, non-ferrous covers is probably not from eddy current resistive losses or partial magnetic flux cancellation, but from something far simpler: parasitic capacitance between the cover and coil windings.

Not sure if any manufacturer has done this, but if the plastic covers are coated (on the inside) with conductive paint or tape, they may also affect the pups frequency response.]]> Guitar Players Discussion gnease https://guitarnoise.forum/guitar-players-discussion/do-they-effects-sound-pickup-covers/#post-84760 https://guitarnoise.forum/guitar-players-discussion/do-they-effects-sound-pickup-covers/#post-84744 Thu, 13 Jan 2005 05:30:44 +0000
That would be pretty cool on a DIY guitar, pups with a veneer over them that's flush with the body... look like a Variax (appears to be pupless) but sounds like a genuine magnetic pup... yeah... I'm digging this already. Assuming that you don't change the distance of the pickup from the strings, yes.]]> Guitar Players Discussion Metaellihead https://guitarnoise.forum/guitar-players-discussion/do-they-effects-sound-pickup-covers/#post-84744 https://guitarnoise.forum/guitar-players-discussion/do-they-effects-sound-pickup-covers/#post-84724 Thu, 13 Jan 2005 03:03:42 +0000

JoeThat's incorrect. Nonferrous metals affect the magnetic field because they are electrically conductive and the fluctuating magnetic field of the pickup induces eddy currents in the metal shield that generate an opposing magnetic field that weakens the signal. Ferrous metals have the same effect insofar as they're electrically conductive. Their magnetic properties really don't bear on this much. Nonconductive magnets, such as those made of ferrite ceramics, don't do this. That's a big reason for the sonic differences between pickups with magnets of Alnico alloys (which are somewhat conductive) vs. those with ceramic magnets (which aren't.)

A cover or baseplate made of steel will affect the pickup's response noticeably less than one of brass or copper, which are more electrically conductive. More conductive = less resistance = larger induced eddy currents = larger opposing magnetic field.
