After I didn't hear anything from Marshall, I contacted Zzounds and told them about my problem and that I would prefer to just return the amp since Marshall doesn't show any interest in contacting me. Even if the correct procedure would be to take the problem up with Zzounds, Marshall could have a least told me that. Instead I get a computer e-mail saying that Marshall will get in touch with me very shortly. That was July 6. 12 days later, nothing from Marshall. This is the ****tiest customer service I have had and it is about as bad as Sears & Roebuck customer service. Marshall lost a first time customer.
