BB605 ground hum..... Any suggestions?

[TRBboy]

Hey guys,

I seem to be getting some sort of ground hum on my backup bass, a Yamaha BB605. If I touch the strings, knobs, bridge or any other metal parts it stops, but as soon as I let go there it is. I've checked in the control cavity and everything seems to be connected just fine.

Has anyone got any suggestions?

Thanks.

I have had 604 and I find the stock pickups noisy as such. They are single coils. Try to set the balance knob in the middle and check the hum again.

Ah yes, thanks Discreet, I seem to have completely missed somehow!

Yeah already thought of that, but it's a slightly different hum and is still there with the blend centered.
