I have an early 70s T-Top in my SG's bridge position. Its a pretty typical double black with a short, rough cast A5 magnet that reads around 7.7k DCR. She has a lot more apparent output than that DCR measurement might indicate. Tight and full lows, open mids and highs that really cut through in a single-coil way with the pickup cover removed. Zero harsh. This pickup really takes my SG to Angus-land. It doesn't have the vocal quality of good PAF copies (or real PAFs for that matter, but who can afford them or even a guitar equipped with them), but that's okay because it does a different classic rock sound that is just as viable. I would not recommend this pickup in a les paul standard or any other heavy carve top with the traditional mahogany/maple/rosewood combination. Maybe in the neck, but not in the bridge. Still one of my favorite pickups.
