I had two PAF Pro's in my JEM DY77. It has a basswood body. I don't know what the pickups will do in an alder body. However, I think they have a very characteristic sound. You can recognise it easily if you listen to the albums of Steve Vai with David lee Roth. They're medium output, respond very good to picking dynamics... can be aggressive... it's how you play them... but for an agressive sound, I think the Tone Zone is more suited. They're very open. In the bridge I found it a little to bright.. I missed a little more lows and output.. but this is also dependent on your amplifier... my JMP1's distortion is not that high gain... However, I think the sound, also clean, is really beautiful! In the neck, it's great! You can do a lot with the volume.
In short, they're great!
