I ordered Power Tron Neck and bridge Pups. The Neck was fine but the bridge casing wasn't installed very well. Replacing Filtrons and had to rout out my DuoJet just to get it to fit. Not only was the bottom casing not tight enough, it was out of alignment so the pole screws cannot be adjusted down through. I could take it apart myself unsolder and resolder correctly but I just took it out. It's sitting in a box on my bench. Maybe someday I'll fix it, but really shouldn't have to. TV Jones are off the list. 2 stars because Neck seems OK.
