The 0760M set was used on virtually every Motown gold record in the 1960s. Donald "Duck" Dunn used the same strings on countless recordings with Otis Redding and Booker T. & the MG's. They're the fullest and deepest sounding bass strings ever made. Packaged using MAP Technology (Modified Atmosphere Packaging) to prevent tarnishing and ensure freshness. NOTICE: This particular set is NOT suitable for basses with bridges that require strings to pass through the body of the instrument!
