I just finished reading the manuals that came with my Low B-1's that I picked up from macmrkt (thanks again, Matin!). All I can say, is "Wow!" I have never seen such care and attention to detail in an owner's manual. Andy calls it an "Owner's Guide", and I suppose that's more appropriate. He really speaks in a useful manner, and provides a lot of insight into how his cabs were designed, and how to get the best out of them. Bravo, Andy! Later, Tom.
