Dumb question -what market need are they filling?
If an amp can be effective and small -then a gigging musician is going to want that in a combo instead of lugging around 2 things right?. So I don't see it being a Club Gigging Live need.
If you want the flexibility of multiple cabinet options for recording, well a studio isn't going to pick a mini head over the usual suspects in their arsenal for tone for a legit recording. plus most modern combos have insert points, loops and speaker ext outputs -so I don't see it being a Studio need.
So what is it for? Dorm and Apartment home recording cuteness? Being able to saturate at low volumes? This reminds me of the Marshall Mini Stack Fad
I'm being sincere here - other than cute and small and neat to look at -What purpose dose it solve that a combo with good I/O doesn't meet and exceed?
Maybe I'm missing something obvious.[/QU
Weight, plain and simple and some people still swear having tubes in the chain somewhere sounds better. Some people may not want to program their phone and download apps and play thru a computer because they come from a generation where those things arent second nature to them and in fact have an aversion to it. Yep, like me.
