Re: Middle PuP Suggestions?
Have you contacted Dimarzio yet? They seem to reply pretty quickly and can give some advice on how the different Dimarzios would interact with one another. Also, per Dimarzio's tech people, they have a 30-day return policy, so, as long as you leave the full length of the lead on the pickup, you can return it for credit (not cash back) on the next Dimarzio you buy. [BTW, I'm not a Dimarzio salesperson or anything, just have some experience recently in trying different pickups and learning through expensive errors!]
Also, if you are not set on Dimarzios, I like Evans single coils and they match very well with the TZ, IMO. In that guitar I use the lower vintage output model in the middle, with the the TZ in the bridge, and a hotter blues output Evans in the neck. It's a good combo. The lower output pickup has a very soft, airy, springy sort of sound.
