I bought this cover for a Boss Katana 50 and also one for an Orange Crush 20RT. 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 these amps. Both fit well, the cover is thick, 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 unplug cable from the amp, the more potential for damage. 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. [This is mostly a duplicate of the Orange Crush 20RT cover review, since I ordered covers for two different amps.
