So I have 3 Svt 8x10's and only 1 has the original Ampeg dolly. I searched around and the cheapest one I could find was about $100. In my mind I feel I could make one and tolex it for way cheaper. Has anyone ever made their own to the exact Ampeg specs.? I wanted them all to stand at the same height since when I use my SVT head it can be half way on each of the 2 cabs. Does anyone have the exact measurements of the dolly and the casters? Thanks in advance.
