I had Vintage noiseless on a MIM Deluxe player Strat, and they sounded excellent. I also have a set of SCN Sumarium Cobalt Noiseless on my Fender deluxe USA. They sound very good as well. You never mentioned your budget. Remember the MIMs have ceramic magnet pickups. If you buy a bridge from another set it might sound different. I am sure you can get a replacement MIM bridge pickup. Did you check the wiring? It might just be a brocken wire on the switch or pickup.
The Blues is alright!
