So I bought an amp for college yesterday (SWR Workingman 10") and I brought it home and played for about half an hour on it, then let it cool down for about an hour. However when I went to play it the second time (using the same bass) there was a loud static hum whenever I took both my hands away from my bass. It was also louder the closer they were to the strings (without touching them.)

Now obviously this screams problem with your bass. But afterwards I tried running the bass through my half stack and it wasn't doing it. I have yet to try it today (currently at work) but I'm hoping I had either a large static charge in my body, or the cable is going.

Any thoughts would be greatly appreciated.
