what pickups should i get to replace the stock epiphone ones. I like blues, blues-rock, rock, and metal.
That's quite a wide range of sound you want. For metal you might want to try an EMG 81 in the bridge.
For an Epi, try the Duncan '59's. (Alnico V magnets). I've had real good experience with those.
Yeah, that is a wide range of styles, but you could also look into the Alnico II's.
Slash uses these, and they are vintage voiced for blues and blues rock, too.
I personally like Alnico II's.

You really can't go wrong with Seymour Duncan.
You and I are mortal, but rock n roll will never die.
