I have a Jackson DK2 on which I installed an EMG 81. Recently, I've been having problems with the electronics - often, the sound cuts out, or there is a weaker signal. If I shift the cable around a bit, sometimes it comes back to normal. I know it's not the cable since I just bought a new one. What could the problem be? Soldering?

Look at it this way- everyone rags on air guitar here because everyone can play guitar. If we were on a lawn mower forum, air guitar would be okay and they would ridicule air mowing.

input maybe, that happened 2 me b4, take off ur input jack and check the wires
God am i devilishly good looking
I checked the wires, everything seems to be fine. I had to solder all of the connections, since it's been working fine until now (I installed the pickup last year).

uh active pickups hmmm... maybe the batterys going dead???, if you leave the cable plugged in weither your playing or not it drains the battery..
Open up the output jack, make sure your tip meets the hot properly.

If that aint helping, check for loose connection or broken connection from all the prongs at the vol pot. Also check for stripped/melted insulator coz if that's connected to something somehow, it'll affect your signal.
