I'm looking to buy a new distortion pedal for my new band, which plays Metal(core?)

Bands like: BFMV, We Came As Romans, ADTR

I'm looking for a pedal to put infront of my Blues Jr Amp.

Budget would be no more than $200.00

Yeah man. The Blues Junior probably isn't gonna work for ya for metal. Check out peavy. And then sell me your the Blues junior. :P: hehe. But anyway. Boss Metalzone, I think, I've heard is pretty good.
