Re: EMG mod
You can either modify the wiring harness to use two 9v batteries in series, or
Buy three battery clips, solder them all in series (in a ring shape), hook the first two upto batteries, and the last upto the stock wiring harness' 9v battery clip.
I like the second route as it's completely reversable.
I found that when I used the EMGs (81 and 85) at 9v they were compressed and very "metal" sounding. Great for metal guitar playing, but kinda limiting. When I first plugged them in I was quite dissapointed.
At 18v they seemed to have quite a bit more headroom. The since the preamp didn't max out so fast they had less compression more dynamics. They also seemed more punchy, I assume this is do to a better attack responce at the higher power level. I found they sounded alot more like a normal pickup than an active pickup at 18v. Now that I've done this, it'll be a long time before those pickups come out of that guitar.
