Cheers guys. I've received some great advice already.

Well I've tested the cab/amp combination with a different bass and replaced the battery in the active bass. Neither seemed to remove the buzz. I tried bass_ferret's suggestion of setting the gain to get sufficient input and using the master volume to control the volume - this seemed to reduce the distortion a little. By a process of elimination I think I've settled on the theory that the tweeter is responsible for the distortion. I've also come to the decision that at the volume levels I'm using I'm unlikely to cause my gear any serious damage. Thanks again for the replies. Ian.

Thanks for the replies. Machines, I think I can probably borrow another head to check the cabinet, so I'll do that. stingrayfan, I'll try your suggestion as well. I am using an active bass and didn't think to check the batery. Fingers crossed that the battery is to blame!

I'm currently using the following set up for low volume practice: Behringer BX3000T (300W RMS into 4Ohm impedence) into an Ashdown 2*10" cabinet (150W power handling, 8 Ohm impedence). I understand that as 8 Ohm impedence is greater than 4 Ohm impedence, the cabinet will not receive the full 300W RMS power which it would, were it a 4 Ohm cabinet. Assuming, for arguments sake, that the amp delivers 150W RMS power into 8 Ohm impedence, then my cabinet should be safe at low/moderate volume. I would assume that at high output levels, the cabinet would be susceptible to damage caused by power above the RMS value. The problem I am encountering is that when I play at low levels i.e. at conversation volume, the signal is significantly distorted. I am concerned that despite the cabinet's higher impedance it may have been damaged because of it's low power handling rating. It is quite possible that I have overlooked an important point in the sticky's in this forum or am being stupid, but any advice would be appreciated. Cheers, Ian.

Hi. I'm Ian from Glasgow. I've been playing bass for about three years or so now. I started off playing guitar and got roped into playing bass in a friends band. Unlike many in the same position I've actually made an attempt at becoming a 'proper' bassist. Gearwise, I generally play an entry level five string Ibanez (GSR-205) although I also have an Ashbory. I play through a Behringer head and 2*10 Ashdown cabinet. Cheers, Ian.
