At the suggestion of a bandmate I bought one of these to serve 2 purposes. It makes it easy to move your amp/cab around and it gets your cab off the ground at gigs. This only cost $10. It's a furniture dolly. I use it with my Avatar 2x12 cab and it makes moving the head/cab around a piece of cake at our practice space. It is exactly the same width as my Avatar 2x12 cab. Yes, I'm getting old....(and lazy).
