So I was thinking of getting a new processor around 150 euro and found the Zoom G2.1Nu that I found quite appealing. On thomann it's 155 euro. After a little more searching I have found the Zoom G2.1MA (Michael Amott signature series) and it is only 99 euro. Question is, are there any major differences between these two effect processors that there is such a difference in price?
2.1NU and 2.1MA is basically the same processor but how come the MA one is such low in price? In fact that is supposed to be a little higher in price!
My Guitar Rig:

> '09 Ibanez RG1570 Mirage Blue w/ DiMarzio John Petrucci Set
> ESP LTD V-50 Black
> Line 6 POD X3 Live
> Dunlop DB-01 Crybaby From Hell
the MA has the features that Amott likes the best. the regular 2.1nu is the base model.
