I bought this cover for an Orange Crush 20RT and one for a Boss Katana 50, because I have 3 active kittens in the house, and don't want them to give my amps a second look. With these covers, so far, so good! I have the pre-designed, standard covers for an Orange Crush RT-20 and a Boss Katana 50. Both fit well, the quality is great, and there is enough room in the back of the amp, where I don't have to unplug the power cords from the amps. to keep the amp covered. This was a worry of mine, as I feel the more times you have to unplug cables from the amps, the more damage you might do. Plus.. it's a pain to have to do that. I don't feel the amp cover pressure on the cord, which is obviously bent downwards, is going to negatively impact the cord. Years from now.. the power cord can easily be replaced, if it ends up being damaged. If there were only a way to keep the guitar cable plugged in also, that would be nice.
