I have (2) GRB-2U… (1)GM-12B…but my G-MIX-L case saved my Peavey PV-14 mixer from sure demise as a “roadie” decided to toss the mixer to a friend… and it rolled out into the street and would have surely ceased working- had I not just recently encased it with a G-MIX-L! As it is… no problems!! Love Gator cases…
