I��ll start off by saying that if you want a cheap pick up cover and you don��t care how it your tone is affected, this product is probably fine, but I paid extra for this particular one because it claimed to be nickel silver alloy which is generally more transparent and suffers less from eddy currents. I grinded a little bit of the cover so that I could get a solder joint to the pick up base only to discover it is copper internally. Nowhere in the description doesn��t mention being plated copper so it gets one star on the grounds of being false advertising.
