That's a disappointment. I had these on my list to try, because I love Gretsch minibuckers in the G5260 baritone and also wanted something like that on bass.
Still try them. If you like the size, then swap the pups for real TV Jones.
Edit: @Patrice B and all others wondering about the TV Jones pickups, to my knowledge, it requires a little bit of sanding on the stock pickup ring, and they will fit. The TV Jones are just a hair wider. TV Jones also has replacement rings as well. I'd just get my dremmel out and sand though. I've been planning this upgrade a while... But other stuff gets in the way so I may just shield/rewire to a rotary switch.
