i have a custom 5 in my prs, its ok, its better than the stock one i guess but still not the perfect pu for me. and as far as the custom custom, i had that in an old brian moore guitar i used to have and i hated it, but some people seem to swear by it. im currently looking for a new set for my LP, was thinking of checking out the rio grande stuff
I think the custom sounds a bit shrill and too cutting in a small guitar or strat type body but in Les Pauls it sounds killer. The custom custom sounded more ballsy in my strat type. I had a custom 5 in a les paul and I hated it I thought it sounde like it was shrill but weak and didnt give me the gain when I played chords.
