Since you're already thinking in terms of Phil Jones and a C2, have you considered getting a Cub? It's basically a C2 with a built-in 100W/110W/120W amp, depending on the model. Then you wouldn't have to worry about spending the money on a separate head, and it will be just as portable and packable as a C2 would be. You could even gig with it, as it has an XLR out for easy board hookup. (I have one, and I have gigged with it a couple times.)On the other hand, the little brother C2 is super compact and can find one of my big luggages on the way back home (or even as cabin luggage). Meanwhile, here abroad, it can serve me as practice amp. When I will be at home, I can go for another C2 and complete the set.
At that point amp head becomes an issue.
