Lil 59 neck, Duckbucker mid (from an Everything Axe set) and a humbucker stamped Seymour Duncan with a sticker that says 59B. What is that humbucker? Just don't see that on any pickups I've looked at. Thanks
Whether the set sounds good is a matter of personal preference, but the 59B will certainly not be out of place in the company of the other two pickups.
I had the Little 59n paired with a full 59b in the bridge in one of my Strats, stock single coil in the middle. The combination worked very well, the 59 isn't so high in output that it completely overpowers the other two pickups.
I traded the 59b for a JB, but I think I preferred the 59 in truth. It's a warmer pickup, lower output, and a bit more versatile.
Make sure you share pics, and looking forward to hearing your thoughts.
