Just last week I purchased a brand new Marshall DSL40cr, and after playing through it for some minutes I noticed a "wind blowing on a microphone" sort of noise coming from it. I did some research online and found out that quite a few people have had the same problem with this amp. I'm guessing you must be aware of this by now and must also have the solution to this problem.
I live in Brazil, so I'd rather not have to send my amp back to where I bought it in the US, but instead take it to a local tech here in Brazil. I just need to know how to solve this problem. I've already talked to two technicians here, but they don't seem to know what to do about it. What have you found out about this "wind blowing sound" problem? How can I fix it?
Thank you for getting in touch, as your warranty is with the dealer you purchased your through, we would recommend you contact your dealer to arrange for an engineer to look at the amp for you.
