    Hi, I played my bass earlier and my amp was fine but I've just had a quick play on my bass and my amp is making a really strange noise in the background.

    It's a kind of gurgly white noise, and it gets louder the lower the notes I'm playing, it happens at all volumes and is persistent through whatever I'm playing. I have a Carlsbro 150W Stingray 1x15 combo. Please help. Any more info you need just ask. Sorry it's not a very technical question but I'm ******** when it comes to amps.
  2. Let's start low cost - when is the last time you replaced the battery in your bass with a high quality battery???

    Oh yeah, it's an old passive soundgear. No battery, one thing I just thought of, last week I was playing it and the amp started to go quieter for some reason so that it was barely audible, I hit it on the top and it went back to normal, I'm pretty sure that it isn't the bass or lead as they both seem otherwise fine.

    As rickbass said - I'd check the bass battery first.

    Next, I'd check that the cord was okay.

    After that I'd fiddle with the knobs on the amp. I have a Peavey guitar amp that does something similar and it's because one of the pots is either dirty or defective. When I jiggle it, the problem disappears.

    I'd try another bass through the amp next.

    I'd probably unplug the amp after that, and plug it back in to see if still happened.

    If all the above failed I would knock the amp around.

    Then I would kick it.

    Then I might throw it against the wall if it were light enough.

    And then I would take it to get it fixed.

    Hope this was helpful.
  5. I'm no techie by any stretch of the imagination either, Gimp. But when a bump on the amp makes it perform differently, I'm off to the tech shop.

    Low note vibrations aren't much different than slugging your amp.

    Yeah, I think I'll take it to the shop...

    And it's too damn heavy to throw it anywhere anyway...:(


    I hate it when crap things happen to my stuff.
