Spector hiss...

I think this would be the right forum for this post but I'm not positive.

I've got the spector bass i've posted about a couple times and the sound is great, but when I let it sit it has a bit of a hiss (or buzz, or whatever you want to call it). If I dampen the strings it pretty much stops it but if I'm not touching them it'll make the buzz. I heard a suggestion it might not be properly shielded but I don't know for sure.

Here's a shot of the control cavity if anyone can tell if this is shielded or not. If not what else may be causing the sound, or how can I remedy it. The bass has Dimarzio pickups and obviously the Aguilar preamp (OBP-1)

What do you have the treble set at? I am not sure if the Dimarzios need a ground or not, you might check that. Does it crackle, or just a hiss?. OPINION: Dump the DiMarzio's and put EMG's in it.

That was a consideration as well when i first got the bass. My only thought was the Dimarzios do sound good. It's not crackling or anything and as I tried to describe it only happens when I'm not touching the strings. I guess it might be what is considered "hot" pickups or something along those lines.

Yes the noise is reduced when I drop the treble, but to remove enough of it there isn't enough treble in the EQ.

I may take it over to Low Down Sound one of these days and get some EMG's for it.

Drop the Treble on the bass and boost it on the amp.

Hard to tell from the black paint. Normally the black coating is conductive but:

To test shield take a DMM and using ohms place the 2 leads against the internal walls. If you get conduction of less than 1000 ohms then it is shield. Lower ohm readings are better.

Also test if the walls connect to the ground of the cable with the DMM. Again low ohm readings are better.
