i don't want to house my wireless receiver in with an amp, because i use different amp heads for different venues. is there a decent case out there that works well for this? some of the cases are so deep it's ridiculous. i had a soft case cut down so it's only about 12" deep, to house a processing unit and it works great but would rather find something off the shelf. or do most of you just leave your wireless receivers unracked? thanks!
