J&M Audio Customer Service
I sent J&M an email about a week ago asking about one of their AMPs. In less than an hour I received an email response from John answering my questions. That lead to more questions and I always got a response back in a short time. Today, New Years Day, I had(hopefully) one last question on the AMP. I sent an email thinking I would get a response tomorrow or Monday, which would have been fine. In less than an hour John responded to my question.
Customer Service does not get any better than that
