There's a huge amount of bashing Mesa (amps, as well as Randall Smith) here, for various reasons. Yes, I agree that they have patented some things which probably shouldn't have been granted because they were 'obvious' - but I'm not sure that any actually had prior use in a guitar amp. (And if they were granted wrongly, it's the fault of the Patent Office, not the applicant.) Yes, I agree that some of their ad copy is way over the top and bordering on nonsense. Yes, I agree that the amps aren't for everyone and can be offputting to people who aren't the sort who like to finely adjust things to get their tone. But Mesa have unquestionably been one of the most innovative amp companies ever, constantly pushing the boundaries of sounds and functionality in a way that very few other companies even come close to, while maintaining well above average quality at the same time as vastly increasing production. Remember that they were one of the first (if not the very first) 'boutique' amp companies, when they started. I don't know if they're number three in the world in production numbers now (for tube amps), but they certainly are in brand recognition. And they're one of only two amp companies - the other is Fender, obviously - who have twice redefined not only what an electric guitar can sound like, but also actually changed the course of music. No-one has done it three times. (Not even Marshall - none of their later amps are really more than an evolution of their first ones, tonally.) I'd put my Trem-o-verb and Blue Angel up against any amps ever made for outright tone, and the T-verb can do so much it's hard to know where to start if you're looking to beat it. I've also had the pleasure of a long conversation with Randall Smith when I was reviewing a Mesa amp for a guitar magazine, and he was a funny, honest and down to earth guy.
