Hey Simon.
I didn't know you had an Emerald in your Les Paul! How is it?
I have a Riff Raff neck in my Gordon Smith Graduate 60, paired with a Black Dog bridge, and that seems like a nice neck pickup that may do what you want. It seems brighter than the Mule I have in my Gibby LP, but haven't compared the 2 side by side in the same guitar :lol:
