I was wondering.. the Ibanez ATK has a 3-coil pickup, which is about the size of a 5-string MM pickup.. but te shape is slightly different.. are there special High-grade ATK replacement pickups ? Bartollini ? EMG ? Seymour Duncan ?? Others ?? I can get one custom made ofcourse ( i know some dude who makes pickups ), but i was wondering if there are off-the-shelf replacements..
