    There really is no way to know without trying it out. What I recommend is getting 3 battery clips and wiring them as an adapter to connect two 9-volt batteries to your existing battery clip.

    If you have a battery box instead of clip, then it will get trickier.

    I recently went to 18v on my set. What I noticed is not so much a change in the sound as a more open sound that increased headroom gives. I don't ususally have the bass turned up very much, rarely half way so as not to overdrive the preamp (I hate using the pad). I like the clean punchy sound that EMG's provide.

    For my style of playing this has not been a huge change or improvement - it's a subtle difference to me, and the bass sounded good before I did it. You may get more out of it with your style. Give it a go.

    If you just have the pickup set, and no onboard preamp, I'd say the difference will be minimal. If you had a preamp, then 18v gives you more headroom for boosting.
     
  6. I just did it to my PJ set and I noticed an improvement in clarity and dynamics. The difference wasn't huge but enough for it to be worth it.

    for a $1.25, it's worth it.

    Not true. The EMG pickups are active pickups, whether you're using an active preamp or not. The additional voltage will make a notable difference in the headroom and "open-ness" of their active pickups whether you have an active EMG pre or not.

    I've personally upgraded several sets of "naked" EMG's to 18v. It made a difference on every one of them. Have you ever done the 18v upgrade?

    I've tried it several times myself, and I could tell no difference on a regular set of emg pickups with v/v/t controls between 9v and 18v. If you noticed a difference, great, but I didn't - couldn't hear it through an amp or recorded (I did before and after comparisons).

    When using emg's with a preamp with eq boosting controls, there was a noticable increase in headroom between 9/18v as I would have expected.

    Finally instaled another batery. I don't have onboard preamp and I'm using passive wiring which come with EMG PJ set.
    After doing A-B test(9V-18V) I've concluded that MuzikMan is right. Also noticed slight gain up with 18V but is not dramatical. For price of 2eur it worth it! ;)
