The Benedetto B6 Jazz Guitar humbucker is a "ring mount" version of the S6 that is naturally-voiced making it an excelent choice for arch top guitars. Perfect string balance, warmth and richness produce tonal qualities that bring out the true acoustic essence of a fine guitar. The unique black-flamed Ebonova covers simulate the natural figuring of the guitar's tone woods.
