I’m a little responding here, but I want to echo the Emerald praise. I put a set in a dark Greco Les Paul copy, and they really livened up the guitar. When they are in a darker instrument, the Emeralds still have plenty of bottom end, but it is really tight, so you can play metal with them. They are voiced for crunchy classic rockon the bridge and fat singing tone on the neck, but they are really versatile due to their tight bottom end and overwound PAF character. They have enough output to drive an amp, but they are not too hot, so they still sound good clean and for lower gain stuff. I did the Jimmy Page wiring, and the splits are really great sounding as well.
