This pickup is naturally-voiced, mirroring the balance, warmth and richness of a fine archtop to help bring out its true acoustic essence. The tone is organic and articulate, and really brings out the tonal character of your guitar. Unlike the floating S-6 model, the B-6 is a standard sized humbucker that mounts like any traditional humbucker. It uses a standard humbucker mounting ring, and is a drop-in fit for any standard sized humbucker pickup route. Designed for use with steel, nickel and bronze strings. Hand made in Santa Barbara, CA, the S-7 uses an alnico 5 bar magnet, and a single conductor co-axial cable.
