Advertising new-design humbuckers for Guild guitars and basses; replacing the Guild single coil pickup on the guitars and Hagstrom Bisonic on the basses.
Guild humbucking pick-ups have new wiring, new controls. Theres a phase switch for reversing polarity on all S-100 guitars. Guild basses have a tone switch to help you get those tight-hard or full-bottom sounds, and anything in between.
Interestingly enough the S-100 pictured has no phase switch, suggesting an older image
