I own an Ashdown ABM Evo II and I love it! I love it so much i'm considering getting the Evo III. HOWEVER, I have found that when I gig my amp actually starts to rattle off of my cabinet. I currently play through an Ashdown ABM 410T. This is discouraging me from getting the newer version, though I love the sound of it. Does anyone else (Ashdown or other brands) run into this problem?
