I Bought this for my SL88 Studio and Grand. I switch between keyboards from gigs to gigs, I often gig with the SL88 Studio (13KG) with my pop band and occasional jazz gig where I need to bring my more piano focused action SL88 Grand (20KG).
There is a big weight difference between the Studio and the Grand but Gator handles every keyboard well. Solid paddings, support and overall build quality is superb.
