Cheapest Metal Core Wheel (*IMPORTANT QUESTION FOR GUITARISTS ABOUT PEDALS*)?

(*IMPORTANT QUESTION FOR GUITARISTS ABOUT PEDALS*)? - cheapest metal core wheel

Well, I have a pedal (BOSS DS-1 Distortion). I think the Boss ML-2 (Metalcore / Metal Zone. Rückmeldesystem Olvido). Can I give a good sound from the combination of both (I'm looking for a tone "Metallica")? It is also the Behringer wah HELLBABE good? Or at least good for a discount? Thank you.
