I just bought a used Yorkville XM200. It weighs something like 60 pounds, but only has a strap handle. The newer Traynor version of the amp has side handles. If I'm happy with this amp and I keep it for a long time, is there some sort of side handle I can retrofit? Something that just screws in without having to cut holes out, since I have no woodworking skills. Has anyone ever done this with an amp?
