i use those for my Ovations. wonderful lightweight cases. the backpack straps are there and handy as heck. they are much more adjustable the the Mini's gigbag straps. only problem i have with them is that it's hard to get the bugs out of the outer fabric... i like to ride my motorcycle deep into the adirondacks, find a nice quiet stream with a waterfall and spend a few lazy hours working on stuff. there's a great spot by lake Placid that i can jump from rock to rock out to the middle, sit with my feet in the water and use the acoustics of the stone wall if front, the waterfall and bridge to the side.....ahh... spring would be nice... crap ! back to the case ! very good protection from the pre-formed foam. extra compartment outside holds the sheet music i'm currently working on. i should get one for a GA or GS...can't decide. thanks for reminding me to look for one !
