I bought this case because I saw another review that said it fit the new Boss Katana 100 head perfectly. So , I wanted to try it. And it does fit very well. This is very well made bag that has found a new purpose. Ariba makes very quality bags that are more designed for lighting gear. but this turned out to be a great alternative way, at a reasonable price to have a way to protect my amp head in transport. As always, the Sweetwater teams dedication to customer service and satisfaction always helps put a purchase from them over the top. i'm very pleased with this purchase and the quality of the product. .
