In my opinion, The Evolution line (Evo and Evo2) is a shredders pickup.
It has extreme clarity and really brings out individual notes and all.
If you play like crap, it will sound like crap. Even if you have enough gain to power through a brick wall.
The Tone Zone on the other hand is a Soloists pickup, great for slurry passages, creamy smooth solos, and arpeggios. Taps come out nice a round, it adds body to the tone.
Not too good for riffsters since it tends to get muddy in mahogany and darker tonewoods. (In my experience, sounds like a bright neck pup in the bridge position in a BASSWOOD ibby)
It all boils down to this:
Evo=Shredders pickup, Great for note clarity.
ToneZone=Soloists pickup, Great for fattening up lead lines.
