1 ProJet 3 months ago Hello Gretsch Fans! I just bought a Pro Jet and wanted to know if Filtertrons can fit in place of the Blacktop Pickups. The surrounds look the same. The older chrome surrounds that were on the Electromatic Jets seemed to be different but the new surrounds look like this swop would be no problem. Probably going to replace the pickguard with a silver one too. Not really digging the Mother of Toilet seat guard. But other than that it's a great guitar for the money.
