I threw this in the bridge of my Epiphone Les Paul LP Special Player ii. The installation was okay until I messed up the grounding wires. That was my bad. I contacted EMG for some replacement grounding buttons. They sent me 2 without charging me anything, which is commendable considering I'm just a normal guy. Unfortunately they sent me the wrong things. I correctly installed the pickup. Just with the wrong stuff. It has this hum that never ends. However, when I play, I can hear the guitar. The sound I hear is good. It has a slightly compressed sound and tons of output. So much that I don't even need my overdrive into the distortion. I found out I'm crap at changing pickups, and that pickups that hot aren't my thing. I will commend EMG for trying to help. That's why it gets 3 stars.
