For a diehard like me it's pretty easy to use and to understand, but i read many postings from 'newbies'that have a problem with the manual, so i think a dedicated book for the rs7000 wouldbe very needed and used.
i treat all my gear with the care and respect it deserves, so for me the knobs ,casing and all is good enough, i transport it to live gigs in a hardcase, and move around in a car... no crapy setups in the clubs, only the best!
The sound is warm and fat! way better then roland gear, and ofcourse it takes the one controlling the gear to understand how to sqeeuze the best sound out of any box.
Without a doubt one of the best investments i bought for my studio in the last 15 years, perfect in combination with computer platform, aswell as standalone!
