Hey guys, I recently got myself an Aguilar DB 212 and needless to say I absolutely love it. Everything about it.....except the casters. They pop out very easily (sometimes just from lifting it). I don't know much about how sound truly works but I was wondering if I put on some of the Mesa casters (which I've heard nothing but good things about) do I need to fill in the holes where the sockets were originally? Has anyone had experience putting these on? Also, sorry if this is in the wrong forum . Thanks! On a side note, does anyone have experience with the padded cover? Would it be sufficient enough to bring on a tour enough to keep the grill from getting destroyed in a trailer?
