Mike, Try disconnecting the ground from your phone and see if the inductive amp still picks up anything. I notice you mentioned a "pair" of phone wires. Why a pair if you only need one wire? I would think the phone co would use just one if it would work. HARMONICA JOHN San Diego PO Box 740613 SD CA 92174 (619)263-6826 God, family, music, fishing, work. Can blue men play the whites?
