I'm selling a brand new lightweight ATA case custom designed for A4. It's the Roadie brand, 4-wheel clam shell designed which you can just pull to roll it. It was never used as I sold my A4 and replaced it with MJPro.
Audya 5 dimensions, i bought that Gator case, nice and sturdy, fits perfect, a little extra room on sides without wedges, but with both the wedges on each side, it is custom, tight fit.
of course heavier than i am used to in nylon, padded bag, but way way more protected, i can actually put light gear on top of keyboard now in truck
