First and foremost, I can confirm that it fits like a glove. It might seem a bit tight at first, but thankfully, due to the DSL40CR's round edges, you can safely slide it in. The material is quite resilient and I've used it to cover the amp for both the sudio and for small gigs. It's not a hard travel case, but it does offer dirt protection and trust me, when you're carrying this thing around, you'll need it. It's a definite companion for the amp.
