Ok, so this is just like an ATA touring case, but for your Ground control pro. Put it like this you could throw it down stairs and your equipment will still be intact.
With good padding inside, the Ground Control Pro can sit snuggly inside and while you're playing, there's no need to take it out of the nest. Just whip off the top and plug in and you're away.
Highly recommend this to anyone with a GCP who gigs with it regularly.
