So I'm looking at boss pedals an I don't really know what to get. I played a few and the metal zone sounded pretty nice. Is the tone on it good?
What other pedals should I look at?
You shouldn't ask us 'is the tone good'... it's how it sounds to you that matters.

On UG, BOSS is a love/hate brand, a lot of people dislike them. Personally, I think they make some alright stuff, I have a few BOSS pedals, and they're great for modding. The Metal Zone is held in very low esteem around here.

Like azrael asked, what's your current gear/budget/tones you're looking for?
boss and digitech are your sort of mediocre pedals.

better stuff like danelectro, vox, divided by 13 etc. are easily located on ebay etc.

Epiphone Hummingbird
Epiphone Futura Custom Prophecy (Twin EMG)
Vox Valvetronix VT20+
Vox Wah
Boss MD-2
Danelectro Cool Cat Drive
Boss EQ
