Si600 Posted April 15, 2016 Share Posted April 15, 2016 Last night during band practice I heard a sort of jangly noise from my cab, it appears around a high F (3rd on D) so maybe frequency based. The cab is a GK MB212, rated at 600 according to the sticker on the back and I run it with the horn switch in the off position. I got if from someone on here, danged if I can remember who, they painted the grill black so if you know who you are speak up! I'm using a GK MB500 Fusion with the gain on B almost all the way up but the master volumes are nowhere near loud, not even earplug loud last night. The signal goes through a tuner - GE-7B - ODB-3 - MS70B - Nova Dynamics Compressor Any idea what may have happened, and is it serious? I'm assuming that if one of the speakers is breaking then replacement is better sooner rather than later? Quote Link to comment Share on other sites More sharing options...
Maude Posted April 15, 2016 Share Posted April 15, 2016 Your speaker cab is haunted by the ghost of Jimmy Saville. If it's not that then I don't know, a jangly noise sounds very strange. Quote Link to comment Share on other sites More sharing options...
ahpook Posted April 15, 2016 Share Posted April 15, 2016 (edited) Maybe you've got some Byrds nesting inside.... [i]Sorry[/i] Does it sound like something loose ? Can you (and a friend, maybe) shake it and see ? Edited April 15, 2016 by ahpook Quote Link to comment Share on other sites More sharing options...
Dood Posted April 17, 2016 Share Posted April 17, 2016 I'd start with loose components too. The front grill is usually a menace - you could remove it completely to check that and if the rattles carry on without it, at least you'l be ready to look for the next loose component inside.

discreet Posted April 17, 2016 Share Posted April 17, 2016 Not familiar with this cab, is it easy to get inside and have a look inside for anything obvious? Quote Link to comment Share on other sites More sharing options...
