This is an Excellent sounding hand wound pickup by Bill Asher. Alnico 5 magnets, 42 gauge wire, 5.8k and 8.9k outputs and Shellac potted. This offers the single pickup Esquire style guitars a better Tone option then just having treble cut caps. More Tele punch with a bit of "Grit" in the 8.9k position and great Tele Twang in the 5.8k position. This also can be installed in a two pickup stock tele and a Push/Pull pot used to switch between both Coil Taps! The Shellac potting offers more Harmonic response and nice Microphonic overtones!
