Hammond organs have many qualities, but portability isn’t usually one of them. The new M-solo, though, is cut from different cloth (and significantly less of it, too).
The M-Solo is said to be in the spirit of the previous Hammond M and L series models, which were themselves designed to draw on the DNA of the classic B-3, C-3 and A-100 organs. The result is “the lightest and most compact true Hammond Organ ever produced”.
