Claim:
1. A magnetic pickup system for detecting the vibration of ferromagnetic strings in a musical instrument, the pickup system comprising: a magnetic pickup that comprises one or more ferromagnetic string-sensing pole pieces; at least one wire coil that surrounds at least a portion of each of the one or more ferromagnetic pole pieces; a magnetic source associated with each of the one or more ferromagnetic pole pieces that creates a magnetic field distribution in each of the one or more ferromagnetic pole pieces; a pickup mounting structure that holds the magnetic source, the one of more ferromagnetic pole pieces and the at least one wire coil in substantially stable relative positions and enables their attachment to the musical instrument; a ferromagnetic tone shaper magnetically but not electrically coupled to the magnetic pickup, the tone shaper comprising at least one ferromagnetic component formed from a material selected from a group of (a) hard ferromagnetic materials and (b) materials comprising at least one granulated ferromagnetic material and a binding compound; and wherein the magnetic pickup and the ferromagnetic tone shaper are spatially separated when the pickup system is attached to the musical instrument.
