I used this with a Hammond SK1, and with that model, the length allowed a built-in separate compartment to "pop up" at the left end of the keyboard for the power supply and cables. This original version of the bag also features a pocket for concealing and storing the backpack straps when not in use, accent protective piping around the perimeters, and the handle straps are different from the current version (please see pics for full details). Excellent condition, made of quality materials, provides svelte transport protection I always envy guitar players having.
