I did a search, and found these mentioned briefly, but is anyone using any form of the Mackie Powered cabs for thier main speaker and amp set up? I have been using the SM450 for small gigs and the SM1530 for larger venues w/great results. I have my pre-amp mounted on my pedalboard, and run a mic cable back to the box. Easy set up, and GREAT tone. Anyone else? Peace, Johno!
