I think I need to build a 1x12 though - I had to lug the 2x12 up a steep flight of stairs in a warehouse/studio last month and honestly it was terrible, ha ha ha
Yes, one reason I really like my Fender Tone Master Deluxe Reverb... 10.4kg!
Plenty loud enough for me, and sounds bloody brilliant.

And who thought a studio on the second floor without a lift was a good idea????
