Well I have the Emeralds, at the moment they're waiting for a Gibson SG guitar which is where they were installed in the beginning replacing the SD 59s and a JB. The sound We were after was Thin Lizzys , even though they played mostly Les Pauls. It turnout to be a tone 10 out of 10 people loved. I changed them for the Warpigs, which eventually lead to lots of complaints. I couldn't be happier with the way they sound. They do what the SD59s and JB cannot......clean, clear, well defined mids that are not overwhelming. Excellent for hard rock.
