I had two of them replaced as well. The first played great but had some cosmetic damage that was done in transit. Even with a bashed-in chassis and pieces broken off of it, it still sounded great. The second cut out once so I boxed it up and sent it back too. The one I have now plays like a champ and I've had nothing but compliments from everyone that's heard it, seen it, etc. I am thrilled with mine. Sounds to me like someone had a problem (probably with one of the early models), got impatient and didn't feel like waiting for customer service to take care of him and tried to modify his amp himself and is now angry about the situation he's found himself in. Understandable to be upset, but to call it a scam ? Come on, man.
