Let's face it fellas, the Hydrasynth Desktop is probably the tankiest synth I've ever owned. I feel like I could toss it across a parking lot (it'd be kinda hard with how heavy it is) and it'd come out working just fine. But, dust, scratches, and little speckles on the screen (yeah I'm a peely boy, I take off the stickers) are not in my purview.
The decksaver does a good job of protecting from dust and scratches, if it's even possible to scratch this behemoth tank synthesizer without a diamond cutter. It's a great Decksaver, it fits like a glove. Your gear costs a ton, you're bound to resell some of it some day, get the Decksaver and keep it pristine (but take off the peely's, heh heh, I'm a bit of a psychopath) and you'll be glad you did.
