These conversations always go the same way on new products. It’s like deja vu
It doesn’t matter what Mesa or any other company makes. They’ll get complaints regardless. Mesa could reissue the Rev C and people would complain it didn’t have a clean channel. They could make a Recto with modes that switched from Rev C - Rev G and everyone would say it isn’t the same without Schumachers. That’s just the modern, online guitar community. You’ll never please everyone.
That said, without going too far down the rabbit hole, amp manufacturers run a business. When it comes to R&D for new products, they have to look at market research and develop a product that straddles production cost with options offered and determine what things to include users will want/need to justify cost so it sits in a price region that makes sense in the market.
For example, could have included midi, it’s within their wheelhouse. But they have to ask themselves - what is the adverse impact of adding this option? How many users will require midi on a 2 channel amp? If we add midi and it drives up the cost of the amp by $300-$400, how will that impact sales?
And on it goes. It’s not a game of just adding options at random and hoping people like it. If they built this amp to the spec I’ve seen half of the people online wanting, it would probably drive up cost to over $3000 for additional options only a fraction of people would use and then sales would be adversely impacted because of it.
The irony of most of the commentary is that a lot of people are describing essentially a Road King with midi and IRs, though I’m sure if they did that and subsequently had to charge $3500 for it, most naysayers wouldn’t bought one anyway, and they would have just eaten into the sales they could have had if it was priced where it is.
Look at a company like Soldano, with the latest SLO 100. They’ve essentially repackaged the same amp they’ve been selling since the 1980s and charge almost double the cost of the Badlander. No midi, no modes, no crazy shit added. Why? Because they’ve made a market determination that they can sell them for $4000 as-is, and if they added the things people claim they wanted and had to charge $5500, they’d sell significantly less of them.
If you want a dedicated 16 ohm tap, get a box like shown above for next to nothing. My tech offered to make one for free the last time he serviced my old Super Lead. As far as midi, what do you want midi for, to change back and forth between 2 channels that any switch can do (and most effect processors have jacks for)? You want to pay $300-$400 more for that?
TL/DR version: Moral of the story - the R&D decisions of companies doesn’t revolve around your individual wants. They’re designed to provide a product they feel will have the most appeal to the most amount of people at a price point research tells them will sell. Mesa doesn’t care if not having midi stops you from buying one. They’ve already factored you into the equation, just like Soldano knows adding a few options for me won’t prompt me to shell out $5000 for one. They’ve already accounted for me.
If you’d rather have additional modes and the other options, then buy a MW instead. If you want midi on it, then just buy a mini amp gizmo on the cheap and you have instant midi at less cost than it would have been to implement midi on the amp
The only difference is you had the choice of whether you wanted to pay for it.
