I have used a dual Tonezone setup in a H-H S520EX before. I don't know how the TZ in neck will balance with the
Evo bridge in terms of tone. The TZ will balance output definately, thought it might be a tad too powerful.

Not a biggie.
A TZ in the neck of an S series turns the
neck position tone into something like a Les Paul's neck tone... uber thick, fat and creamy! Its insane. You can flip it around for a more trebly, slightly thinner tone but its not as neck-ish as a neck pup should sound.
So yeah, because an Evo is trebly and kind of harsh sounding, you'll have a very contrasting neck pup tone... would you like that? If you do then go ahead.
Oh yeah, a TZ in the bridge of an S series works nice. No mud just chug.
