1: Only the well heeled and well connected will EVER get a chance to buy one of these from Mesa. At the very minimum, I expect nobody who isn't at the level of a social media influencer to be given a chance to make a deposit for one. I'm a nobody, and will never be presented with that opportunity. But I would, today, if given the opportunity.
2: The notion that the run will be limited due to parts availability is nonsense. It'll be limited to keep prices up. There's not a part in a Mark IIC+ that can't be reproduced exactly or replaced with a 100 percent good workable substitute.
3: There's NO evidence, not a speck, that Gibson plans to send amp production overseas. Mesa was fortunate to be bought by Gibson, of all companies, because Gibson is far from perfect but at least understands the value of "American Made, World Played" and has been steadfast in its commitment to American manufacturing of Gibson guitars. It's a corporate value with Gibson and I don't expect them to allow Mesa amps to be outsourced. Not at any time in the foreseeable future. Mesa does very well by selling only a premium amp line, the cheapest of which is still 1300 or 1400 dollars. No other big name amp company has such an expensive overall product line, and yet Mesa is doing strong business.
