I searched for this topic, but I couldn't find one that addressed my question. I am looking into getting the Ibanez sz720fm, but I am thinking of replacing the pickups with EMG's. The debate comes between getting an 81/85 set or an 81/60. I was a wider range of tones. A crisp clean and a dirty distotion. I think the 81/60 combo would do that but I am not sure. Also I was wondering that, since they are active pickups, how a battery source would work with it, or if it needed one. Thank you.
I would check around that you can fit a battery in the electronics cavity with the pots and wiring. Unless you want to route your guitar, you will need someplace to put the battery. I've installed them in a lot of electronics cavities on superstrat bodies, but the S is a pretty thin body.

I would go for the 81/60 for what you're after.

the 60 has good cleans.
the 81 has killer distortion.
they need a battery.
you should check to make sure a battery will fit in one of the cavities.

also, I was wondering about how the battery life was for active EMG's.

Please if you make the comment that there are better pickups other than EMG's supply me with a few examples to accomplish what I am looking for. Thanks.
Where are you located? if you're in the UK, the BareKnuckle pups are fantastic, they're just really pricey in the states.

My batteries typically last me about 4-6 months depending on how much I play them. I've never had them actually die, they just start to sound a little flatter than normal.

How long does the battery last?

All EMG pickups and EQ systems are designed for extremely low current drain. In addition, the pickup jack included with all models has a switch that disconnects the battery when the guitar is not plugged in. To maximize battery life, you should always unplug your guitar when it's not in use.

The Specs Page includes current requirements and estimated battery life for each model. Generally, each pickup requires about 80 microamps (uA), except for the Vintage Series pickups which require 220 uA each. EQ circuit requirements vary widely but are higher than pickups.

For your reference, a standard 9 volt alkaline battery provides 580 milliAmpHours (mAh) of power. That means that it will provide 580 milliAmps for 1 hour or 1 milliamp for 580 hours. There are 1000 uA per mA. You can figure the approximate battery life of any setup by adding up the individual power requirements, then dividing 580,000 by this total. Here's an example:

1 - EMG-81 = 80 uA
2 - EMG-SV = 220 uA*2 = 440 uA
1 - EXG = 410 uA
Total required = 930 uA

Total life = 580,000 uAh/
930 uA = 623 hours

If you left your guitar plugged in day and night, the battery should still last a month. Under normal playing conditions, you would probably be looking at changing the battery twice a year. Of course, you should treat these numbers conservatively and not try to drain every last uA out!
