hi, i am considering buying a yamaha magicstomp box and i have heard its best to get the latest version which is mark 2 or something. on ebay many of the units don't state if they are mark 2 or not. is there a way to tell just be looking? i have seen some black and some purple units. does this have anything to do with model?

also does the magic stomp have headphone socket and a built in noise gate? cheers
