I have a quite dark les paul with Rebel Yells, tunned in drop C (12-52 string gauge), it sounds great, massive modern rock sound, but sometimes I feel like missing a bit in the medium/high and high end spectrum. So I'm thinking in moving the RY to my brighter PRS SC245 and get something more shining for the les paul, maybe the Cold Sweats, maybe the Black Dogs
I think the RY should match well with the CU24 too. The Abraxas should work great too, you'd lose a bit of output but get more clarity and definition in return
