Try a UOA5 in it. It will cut the highs just a bit like the A5 vs. Ceramic, but it will give more mids.
The Custom is a fav of les Paul users. It's louder, punchy, and more powerful than the Custom 5.
Got it,put it in tonight.Like it! Pretty good as is.But will go with UOA5 pretty soon. Alinico ii pro in neck makes a nice match.
uoA5 is a fantastic choice. I have a uoA5 custom in my prs se singlecut, and love it there. it's paired up with a dimarzio 36th anniversary in the neck position, and they make a great combo. I imagine it would sound great with a number of the Duncan PAF-style neck models, as well...
