D'Addario EXPR170 Reds Bass Guitar Strings react much like a standard electric bass guitar string where the outer wire is highly magnetic, but the copper coating imparts a more “acoustic” tone on basses with magnetic and/or piezo pickups. The EXP coating protects the copper windings from corrosion and premature wear. A modern version of an original D’Addario product offered in the ‘70s, EXP Reds use a proprietary outer wrap wire made of copper coated steel which is then micro-coated utilizing D’Addario’s EXP technology. Like a standard electric bass guitar string, the outer wire is highly magnetic, but the copper coating imparts a more acoustic-sounding tone on basses with magnetic and/or piezo pickups. The EXP coating also protects the windings from corrosion and premature wear.
