Yes, very noticable. Its a 1994 lp custom from the samick factory in korea. The old pickups had no definition whatsoever, were muddy and farty sounding to the point where i didnt want to play it. Now it has stock electronics from an lp trad plus with coil split push pull volume pots. The neck pup is actually usable and the bridge is crispy and powerful. Those epi hbs werent driving the amp at all. Now i own an epi im not ashamed to play
