Selling my black bridge position Harmonic Design Z90. Very good condition, output measures 10K. These pickups sound great, just don't have a need for it any longer. The Z90 is a humbucker-sized P90-ish single coil, lots of info on Harmonic Design's website. I'm not sure of the year but it is a more recent version with the sealed plastic cover (earlier versions were more like an open coil humbucker with tape on the side) $90 PPS in continental US.
