Anyone know what's up with the shortage of Gretsch filtertron bridge pickups? I have a strat that I have a few different loaded pickguards for it. One with Lindy Fralin vintage hot strat pickups, and one with two Lindy Fralin Sunbucker Blues PAF. For about 6 months I've been thinking of doing another loaded pickguard with Filtertrons. However I can never find the bridge version anywhere I look. Sweetwater, GC, Reverb, ebay... nothing. Neck versions aplenty, but no bridge. This for a guitar I don't play that much anymore, so I'm in no hurry, so I don't scour the internet every day. But still what gives? Anyone know the reason for this? Cheers!
