I just picked up 2 Gretsch Filter'tron PAFs. I haven't received them yet but I was wondering how they sound compared to the current ones

Any idea of the age of these?

Mine sound amazing. Way better than current HS Filters. They're a little lower on output volume though.

They are from 1959. I'm trying to decide which guitar to install them in. Maybe I should get a new Gretsch to install them into. I have some vintage Super'trons as well and they sound great.

They're probably lower in output because the magnets are decaying, which basically would mean more twang and definition, ideal!!!!!!!
