I like th elooks of my LSC 2x12, but it is heavy. Mesa did tell me they sell the empty cabs and heads separately. The long head is $250. They told me that the chassis is the same in all the LSC styles so you can change the cab with no problem. It will work in the short or long head as well as any of the combo's.
I was thinking of getting the head in black and then an Avatar or TrueTone cab in black with a Fender silver grille cloth. That would cheaper than the Mesa cab by itself.
The cabs are heavy even without the innards. When I shipped my LSC chassis back to Mesa it was just over 30 lbs, and the cab with 2 speakers was heavier than the chassis.
Just a thought.
