JAZZ ROUND WOUND - BASS GUITAR This unique sounding string gas a construction very similar to it's flatwound counterpart butwith slightly more edge. The round outer-wrap is a small diameter nickel alloy winding which ads slightly more bite to the upright style tone without the typical roundwound side effects of excessive string squeak and premature fret wear. The set is designed with a lower tension and gauging to increase ease of playability and reduce strain on the instrument's neck without sacrificing output.
