So I finally plunked down a couple of GC gift cards and some hard-earned cash to get a used MarkBass CMD 121P, as per my bass teacher's recommendation for a small, light, loud amp. I got it for $600 used! I'm excited, but I still need to figure out how to transport it. 30 pounds is still about twice what I can handle with one hand (yes, I tested this out with a big container of cat litter! Haha). So do they make a rolling case for it, or should I just use my cart...? Any ideas?
