With some help and good advice I have successfully installed
DiMarzio Tone Zone 7 and Air Norton 7 into a new Ibanez 1527CB.
Holy crap

Amazing! Body mounted axes rule. What incredible tone. This 1527 just has this amazing tone in bridge position! It's got that old school Growl yet has this essence of harmonically rich overtones. It doesn't loose it's self in the mix. With light palm muting the percussive qualities in the low register are simply huge.
This purchase was a gamble for me, I've tried Evo 7's and found them to bright,,, maybe even a little to clear. I have had old school Blazes that are stock in my old 91 UV777GR. So that machine for me is the axe by which all others and measured. What a combo, the 1527 is a sleeper, a players 7 string for sure. What a value I got with the prestige specs and amazing new pickups.
The Air norton is rich and warm. It doesn't seem to have the percussive qualities I had hoped for,, but then again I have new strings on it which tends to brighten things up a bit. There is that sweet spot that we all know and love with new strings. You know the spot when you have had them on for a few days and the brightness gives way to warmth. Yep that is what I am waiting for with the Air norton. However the air norton has a quality that is just as harmonically rich as the TZ but in it's own way, it very subtle in transition in distortion from bridge to full neck. The sustain is insane. Body mount, new trem all accomodate very well to the sustain I'm sure.
The Clean tones are where is really obvious with this combo. 1st position ( bridge ) TZ,,, whoa! loud, warm and crystal clear, coupled with delay and chorus.... awesome. Harmonically insane! 2nd position! Oh deay! We are talking "EAR-GASM". Warm, balanced just incredible depth. Mid position warm and a little less enhanced just tighter with more mids very nice. 4th position! little more warmth, you can tell the you are approaching the neck pickup,,,it's got an almost twang to it when you pick heavy,,,"ala, Stevie Ray". 5th position,,,powerful warm and clear,,, all the way up and down the neck there is something about it that makes you just giggle.
Speaking of giggles! The TZ7 is just a monster with a Bad horsie! I've been sort of happy with my Bad horsie for years. I loved it when I had Jems,,, Evo's, Breeds and Pafs! Awesome! However with the 7's it sort of seemed to loose mudulation. I couldn't seem to hear all the bad horsie through the entire travel of the pedal. The
scooped mids on the Blaze are awesome but seems to hurt in that small zone on the wah pedal that is soooo saught after. Not with the TONEZONE though!

BOING! The raised mids and bass work super with the Bad Horsie,,,, it now talks! That sweet spot on the BH somewhere just about at the middle of the pedal brings out these huge harmonics! Whoa! $*@§ man just about fell off my chair. Step on that pedal! There is no doubt that you stepped on it.
I have to agree with DiMarzio on the adds for these 2 pickups. "These are not just copies of the popular 6 string p/u's". They are made for the 7 strings in the vein of what the 6 string versions offered. They are both very well thought out! KUDOS! My only complaint is with all the new offering for the 7s would have to be " I WANT COLORS" Purple, blue, green, pink and everything in between. That's the only thing that would have pushed me over into complete bliss. Color options on these would be sweet. Other than Black, creme or black and creme. Regardless it's about the tone and with that I'm thrilled.
