Hey guys i'm looking to purchase a new distortion pedal for my Peavey Classic 30. The amp itself does not have enough gain in my opinion for most stuff i'm looking to play however I like the cleans.

Im currently using a Boss MT-2 MetalZone pedal for my distortion when playing metal and to be honest it sounds rather terrible and I am aware it has a bad reputation around these forums.

What pedals would you reccomend for playing metal such as Opeth, Machine Head, Trivium etc?

a blackstar dist-x
Ibanez GSA60
Epiphone SG/LP custom
Schecter Damien elite 7
Fender Highway one Telecaster

Visual sound Jekyll and Hyde

Peavey 6505
Marshall M412a cab
Peavey Classic 50
