aLxbass

I have checked they seem ok.. they are both panasonic 9V ?

Hi, the other day I got my 406QM!
I love it, brilliant bass.. looks gorgeous and feels great.

But theres one problem...

when I play it through my amp (Laney RB2) it makes a horrid rumbling noise unless I pluck the strings extremely lightly..
I was wondering is this because my amp sucks or is it a fault with the electronics on the bass?
Bare in mind my other bass's are fine on this amp but they are all 4 strings and the majority of the rumbling noise on the low B string.

Oh, and this is the only amp I have available at home so i can't trying it on anything else at the moment, was just wondering if its a known problem?

Thanks, Alex
