basskit_case Posted March 29, 2020 Share Posted March 29, 2020 Hello All, After a longĀ while I decided to plug into the LB30Ā for a change instead of using headphones. When I power on I just get a an electrical interference sound, tried multiple cables and different sockets. the sound is not so pronounced if I disable the bass shift on the eq. All valve are š„. Any ideas if this Would this beĀ a head or cab issue? thanksĀ Ā IMG_5830.MOV IMG_5828.MOV Quote Link to comment Share on other sites More sharing options...
Reggaebass Posted March 29, 2020 Share Posted March 29, 2020 Iāve got anĀ LB30 and I had some interference once, it turned out it was a dodgy cab lead , but you said that youāve tried that , maybe @Ashdown Engineering Can offer some advice š Quote Link to comment Share on other sites More sharing options...
pete.young Posted March 29, 2020 Share Posted March 29, 2020 Under normal circumstances I'd say bring it round and we can try it on a different cab & lead, but I don't think that's such a good idea at the moment. Could it be dirty jack sockets in the effects loop? I've heard of that causing trouble with other equipment. Quote Link to comment Share on other sites More sharing options...

Dropped ash down an email directly too If you have some switch cleaner, spray it onto a plug and put that in and out of the socket a few times, has been known to work occasionally!

wateroftyne Posted March 31, 2020 Share Posted March 31, 2020 Does it make the noise without your bass cable being plugged in? Ā Quote Link to comment Share on other sites More sharing options...

mickster Posted April 6, 2020 Share Posted April 6, 2020 Do you use ethernet plug extenders in your house? The things that use the mains wiring to transmit network computer traffic? I had a static noise on my LB30 - did the usual effects & jack cleans, changed tubes etc and it turned out it was picking up noise from the network extender thingies...

I have to unplug them when recording. (it's not an issue with Class D heads, just tube and A/B) Quote Link to comment Share on other sites More sharing options...
