Jimryan Posted February 28, 2013 Share Posted February 28, 2013 Afternoon all, This has been driving me mad for a while now. If I run my gear at a low volume, it's fine, but when it's loud, it's a different story altogether. It buzzes and rattles...big time. I've dissected it all today, coated the handles to stop them making noise, re-sealed both front and back panels, checked the rear of the driver and checked all the screws for tightness. All of this helped, the rattle has near on stopped, the buzz is still there, but it's now developed a slight distorted sound. Which would be fine if I used distortion, but I don't. It's doing my head in, I can't find a solution at all and I've got rehearsal in 3 hours... HELP!?! Quote Link to comment Share on other sites More sharing options...
neepheid Posted February 28, 2013 Share Posted February 28, 2013 There aren't any wires hanging down from the drivers and making contact with one of the cones? This happened in my Zoot cab. A second pair of eyes (thanks, Rich) a couple of cable ties later and the problem was solved. Quote Link to comment Share on other sites More sharing options...
Jimryan Posted February 28, 2013 Author Share Posted February 28, 2013 Nope, checked that and made sure whilst I had it open. Quote Link to comment Share on other sites More sharing options...
MiltyG565 Posted February 28, 2013 Share Posted February 28, 2013 The cones aren't damaged, are they? Quote Link to comment Share on other sites More sharing options...
Jimryan Posted February 28, 2013 Author Share Posted February 28, 2013 Nope. The cone's fine. That's why I'm finding it so frustrating. I can't think of anything it could be. Quote Link to comment Share on other sites More sharing options...

brensabre79 Posted February 28, 2013 Share Posted February 28, 2013 Has it got an open jack socket? Quote Link to comment Share on other sites More sharing options...
Left Foot Posted February 28, 2013 Share Posted February 28, 2013 square wave invader! I had to sort out my bass pots recently to stop this happening, I thought it was the amp cab but it was the pots. Quote Link to comment Share on other sites More sharing options...

whizzzy Posted March 2, 2013 Share Posted March 2, 2013 Another thing to check is the flexible wiring between the chassis of the speaker and the cone. Sometimes they are situated at such an angle where they rattle when the cone is moving. Gently move the two wires where they connect to the terminal post or tag strip by about 3 - 4mm and see if this resolves the problem.

hamfist Posted March 6, 2013 Share Posted March 6, 2013 Jim, you've probably sorted thi sout now. If not, it's possible distortion may originate in the amp. Have you tried a different cab, or amp ? Quote Link to comment Share on other sites More sharing options...
Jimryan Posted March 6, 2013 Author Share Posted March 6, 2013 I've reduced it considerably by placing weight on the roof of the cab when using it. It's defo the cab. Quote Link to comment Share on other sites More sharing options...

3below Posted March 7, 2013 Share Posted March 7, 2013 If it is the walls of the cab you may need to glue some bracing inside the cab. Fairly simple to do. Quote Link to comment Share on other sites More sharing options...

Gluing in some 3.4" or 1" dowel, something like this [url="http://www.talkbass.com/forum/f15/carvin-ls1503-bracing-731252/"]http://www.talkbass.com/forum/f15/carvin-ls1503-bracing-731252/[/url] (post #8) should sort it out. If it's a cheap cab it may have no bracing at all currently. Quote Link to comment Share on other sites More sharing options...
bertbass Posted March 7, 2013 Share Posted March 7, 2013 Some of the glue joints haven't broken down have they? Might be worth checking that all the edges and corners are still solid. Quote Link to comment Share on other sites More sharing options...
