i use a slightly overwound traditional style a5 tele bridge pup with my antiquity ii firebird neck pup, 250k controls, and they match up well. you could use something truly vintage output, but the output and tonal balance wont be as even. i like the jd in the bridge, a broadcaster could work too if you wanted something brighter and more steely. a hotter pup like the qp or hot could match up fine and bruces suggestion of a bucker works well too depending on what tones you are after.
the firebird might be about as hot as a filterton but i havent a/b'd them, a vintage firebird pup is hotter than a vintage strat pup for sure
