Designed by bassists in the office and road-tested by bassists from our Artist Family, Round Core Bass Boomers have a full frequency sound (generous in the low mids) with a clear, soft high end. Nickel-Plated steel is wound over a round core, providing a more tactile feel under your fingers. With a balanced construction with the G/E strings, Round Core Bass Boomers are consistent across the entire fretboard.
