There's a lovely way around that however, rack the head, rack panel in the cab, same sublime sound, but instead of a single-unit rig weighing a lot you have a dual-unit rig with each component pretty light by comparison
Having said this, I'm very happy to keep the cab, it's as sublime as the head, and having a couple of other sublime heads to use with it, it's not going to sit unused.
Either way, and all discussion of weight aside, the Carbine M6 head ain't that much heavier than most and is an absolute steal at £550 👍
