The Guild BS-1 BiSonic pickup was originally found in many of the solid and hollow body Guild basses in the 1960s and 70s. The BS-1 has developed a cult following resulting in several reissue versions and designs, including the famous Darkstar by Fred Hammon and BS-DS by Curtis Novak. Wound to 6.4K Ohms, similar in specification to a Hammon Darkstar, the Guild BS-1 provides a refined modern tone in a classic package.
