This is not a Synergy Core. I've used it for about four years, mostly indoors, so there are no major scratches on the exterior. The accessories are as shown in the photos. All original accessories (adapter, USB cable, and instruction manual) are included. I'm also including the following extras, but please let me know if you don't need them at the time of purchase. They cost about 20,000 yen in total. - TB2 cable - TB2 to TB3 adapter - ADAT cables x2 - A/D converter + adapter - D/A converter + adapter
