Whenever you're getting anything that's going to modify your guitar's sound make sure it doesn't mask your guitar's original tonal properties. A good example would be one of those digitech multi-fx units. There are some interesting things you can do with one, but not only do they not sound very good they sound the exact same when you plug in a $2-digit squier with 2 year old stings through it as when you plug in your custom neck-through korina les paul. It's messed up.
I haven't played around with the boss metal zone yet, but I did hear it a long time ago and I recall liking it a lot. I sucked at guitar then so I would like to get my hands on one now for comparison, but I gotta save up for a coat first :(
