two of my clone amps fit in perfectly. It is made by Tourtek. I also think you could use it for one amp and a bag of extra gear(tuner,cords) would fit nicely above the single amp. The sides are canvas with an insert to stiffen them.
I like it for the price, only thing better would be a flight case, but also a bunch more money. I may add an insert between the amps to help protect tthem
