Yes that is the base unit to the Bose Compact, bottom photo another angle.
Donny, sometimes I do stand up the equipment case to level off the keyboard. I usually take the Guardian right off the the RnR cart to unload. The extra length of the 76 key case touches the the handles on either end makes it a bit harder to remove the keyboard while on the cart. I miss being able to use the 61 key model for T4 that I used to use with the s910.
I'm with ya on the Guardian case, I love it, light weight lots of protection but strong.
