How is that even a question? Mesa will make their own business decisions. They know their marketplace and they have been running a successful company, with pretty high prices, for 50 years. A few years ago I remember walking around their shop in Denmark Street and almost every guitar combo was over £2k. You can dislike their pricing policy but comparisons are futile. If only Aston Martin reduced their prices I could buy one, instead of the old Volvo I could afford!
25 years ago Mesa certainly did assign and enforce retail prices, well in the UK and at the Bass Centre, they did. Grant complained about them, a lot. Then again, people can pay just as much for their cabs and significantly more for their basses. Many big valve amps are north of £2K so the headlining, feature packed D class amps could be said to be on the more reasonable side of that comparison. But still, owning certain gear can be an expensive decision. You decide which marketplace is for you and then normal buying decisions apply.
But if you're a Ford Focus guy why worry about the cost of a Range Rover?
