So I bought a Gallien-Krueger RBH 410 cab off of craigslist today (my 2nd rbh in 4 years) but it didn't come with the casters for the bottom. Considering its weight and my need for portability I'm stuck needing casters but I'm not anxious to buy a new set of oem GK wheels because of their notorious unreliability and being prone to breaking. I've heard of guys buying and installing wheels from a local hardware store but i've never seen anyone happy with how they turned out. Has anyone had success replacing their oem casters? Any recommendations of what to get?
