Ditto on the placement. Either the window or corner of the room for me when I can!Good amp placement goes a long way with these. I had one once pointed back at a window and it reflected the sound back amazingly. Small cafe gig but people thought I was going through the PA.
I was using my MB Minimark, but upgraded to an Acoustic Image. But I'm never gonna give up the MB. He's way handy for a lot of other situations.
