Bass Surges?

Hey,

Don't know how to describe it. I can lay my bass on my bed, all the volume on full, plugged in, and amp is on, and every ten minutes or so I hear this random surge through the speaker. It's almost kind of a "zap" noise and lasts less than a second and goes away. I have noticed it when I'm playing but not as much.

I'm wondering that it's likely the cable, but I also noticed the other day that my volume knob has some static on it when I adjust it very quickly at loud volumes.

My setup is basically what you see in my signature, I have a 20' long 14 AMG cable running from my bass to the VT Deluxe, the RGE-10 is a graphic EQ which is in the effects loops of the VT hooked up with two 1/4" to RCA connectors (the RGE takes the RCA connectors), and then a pretty thin 5' foot 1/4" cable going into (right now) a 10 watt VOX guitar amp.

Anyone have this issue before? Any solutions? I'll try another cable now, and see if that helps.

the power supply going to your bedroom might not be consistent, i have the same problem with my washing machine in my basement, in my case the power provided to my house by the city of LA fluctuates a lot, i learned this from the sears repair guy showing me his volt meter, it effected my mesa tube head in the studio as well until i started using a fancy power strip i bought at radio shack

Hmm... That sounds logical, as my house certainly has dated wiring (knob and tube to be exact), but I never heard this before I added the VT Bass Deluxe and Boss RGE-10 into the picture, but I do have power supplies for both of them, and that little extra amperage could be causing it. I sincerely hope that isn't the issue as I have a Crown XLS1000 sitting around collecting dust while I wait on 410 cab. I do have everything plugged into a power bar, but it is a basic and relatively inexpensive one.

I have bypassed the RGE-10 (which is likely 20 years old) for the last half an hour or so and though it is still getting electricity it is not in the signal chain. I have not heard this surge since I've done it. But, I still do hear a brief kind of disruption in the static coming from the speaker which is just as frequent as it was before and it lasts just as long... But I could be hearing things...

Maybe the RGE-10 heightens the frequency and causes it to be heard? I don't know, but I can't hear that surge at all and when it surged before, it was quite noticeable (it was nearly as loud as tapping a string). I don't know if the RGE-10 would exagerate the frequency that much.

Or maybe the RGE-10 is just old, and there's some loose or corroded terminal or something. I'll keep it bypassed and make sure I don't hear it again.
