Abstract
A method of treating a nylon or other non-ferromagnetic musical instrument string so that its movement is detectable by a ferromagnetic pickup includes applying ferromagnetic material to a portion of the string when the string is mounted to an instrument. The preferred method is to paint the string with a fluid material comprising a suspension of nickel particles in a solvent, and permitting the solvent to evaporate to leave a residue of nickel particles on the string.
