I'm leaning towards a Boss ME-50/20/70 money and personal preference wise.

I wanted to buy it 'cause it has a good range of tones aside from everything else that make it brilliant.

However, I've learned that it's the best for Heavy Metal, my main genre of music.

Is this just a myth, is the pedal good at Heavy Metal?

If not would it be wise to purchase a Distortion stompbox along with the pedal?

Helps appreciated =]
