Guitarist seem more often than not to be unable to listen to an amplifier and determine if it sounds good to them. They seem to only be able to tell if it sounds familiar to them, as in Marshall or Fender. They aren't listening to what they are hearing, they're listening for what they "expect" to hear, what they've heard growing up. How many user reviews have you read where the author states in some form " cuts through the mix well, plenty of gain and responsive tone stack, but it doesn't sound like a Marshall"? I've heard people laugh at the fact that most of the amp builders in say VGM are mainly copies of fender designs but if someone dares put up their new desigh, no one is interested if it isn't a "classic" amp that they are very familiar with. Discuss at will your thoughts and observations.
