FWIW, here are a couple photos for you.

The power cord and speaker cable fit easily in the side pocket (power cord + two speaker cables would be a tight fit). I have a wireless rig in a rack and a homemade pedalboard snake that I carry in the same rack, so I'm eagerly awaiting the rack ears for the WD 800 myself. Until then, it'll be carried in this case.
I have not yet played the WD-800 through my GK Neo 410 cabs, but this amp makes my P-bass sound great through an Energy 115 (or 115 + 118) set up. At this point I am not missing the GK MBF 800 that the Mesa WD-800 has replaced. Joe Bob sez "Czech it out!"
Cheers!
