The Seymour Duncan Custom is a medium output humbucker pickup that features a small ceramic magnet and custom-wound coils to dish out a ‘P.A.F.-on-steroids’ tone. It has tight lows, a bump in the upper midrange that gives you more character and crunch, along with an airy high end that cuts through heavy distortion but is also great for achieving crystal-clear clean tones. It’s especially suited for warmer-sounding guitars with a prominent midrange. Therefore, many players like to use it in Les Pauls and Paul Reed Smiths. It also pairs well with the Jazz or ’59 neck models.
