hi, i was interested if anyone has any experience with the gibson dirty fingers pickup. i am thinking about dropping one into my epiphone dot however i am nervous that it has a ceramic bar. i did not particulary like the seymour duncan invader which had a ceramic bar. does anyone happen to know whether they are tonally similar ? if the dirty fingers sounds like a hot rodded seymour ducan JB than i would be more than happy. but again im trying to stay away from the invader tone . thanks for any help
