EMG PA2

This is a great product for giving the guitar the extra bite and mids.

A word of advice: when installing this, don't set the boost at maximum (you'll understand what I'm referring to when you're there). I had it on max and it just made the guitar sound terrible and over distorted (much like the "loudness-mastering" on Metallica's Death Magnetic). Begin at 50%, try the guitar throught the amp and adjust upwards if needed.
Also, think about this before installing it: do you want it to activate when flicking the switch down or up? If you know that, you can put it in the right position from the start.
I wish I had this boost in all my guitars...

I got EM81 bridge and two passive.
So i needed a preamp for passives, because blending passive and active is a bad thing (tested it...horrible).
I used the other side of my selector for passives, and put PA2 at this side's output.
And soldered PA2 output and other side of selector output (EMG81 side) between them.

I put both PA2 and EMG81 at 18V (they handle up to 27V), and a 9V-18V switcher instead of tone knob (metalheads don't need tone knobs :D ).

Nice solution to avoid bypassing passive pickups or replacing them by active single coils.

I ordered and installed with an EMG 85.
To be honest, I have no need for a built in booster.
My idea was to go for the 18v mod with the 85. So I needed another battery clip. If you check the price of an EMG wire kit, its more expensive than the PA2. I only needed the battery clip and with some extra research probably I could find a cheaper solution rather than buy a PA2... but I thought it will be fun to have this little boost in my guitar (plus I dont have cover an extra hole with ducktape).
I play alone and I not gigging, so I not using it much, but in live situation it will be useful for sure.
Don't turn it max, it will be a bad experience. Around half way the ideal.

Its a good to have little stuff. If you play solos, surely go for it!
