Custom 8!!!!!! If I have to say a production model, Id say a Custom, cuz I can convert to a Custom 8!!!! LOL! I have them in about 8 guitars now! I do also love the new Hybrid TB16!
Honorable Mentions: Strabro 90 (best strat pickup I've played), P-Rails (does everything well), Pearly Gates Neck (the Seth Lover for people who play at ear bleeding volumes)
My favorite is definitely the Brobucker. In the bridge of my LP, it's big and in charge. Cleans are great, but drive through my Box of Rock can't be beat.
I can only pick one! I gotta go with the Blues Saraceno PATB-3. Smooth even frequency response. Not too much of anything. Not too little of anything. Perfectly balanced.
