Boss ML2 Metal Core Effects Pedal



Boss ML2 Metal Core Effects Pedal

The Boss ML2 Metal Core Effects Pedal finally offers the grinding, thick distortion that is so necessary for metal. Many ”metal” distortion pedals simply offer an excessive amount of gain and slap the ”metal” moniker on the pedal- not the ML-2.

This pedal has been designed with the sole intention of being heavier and fatter than any distortion pedal previously, and that includes more than just increasing the gain. The tone and attack of the whole pedal has been shaped to be razor sharp to cut through even the most congested mix with ease, the tone control is incredibly responsive however and it’s possible to dial this back all the way for sludgier, doomier tones.Of course, the ML-2 does have gain on tap and can get ridiculously hot at higher levels but its the attention given to the rest of the design being tailored just to metal players and heavier musical styles that makes the ML-2 so special.

Metal to its Core

You’d be hard pressed to find a metal subgenre this pedal doesn’t suit- from blackgaze to goregrind. The Boss ML-2 Metal Core Effects Pedal dominates the competition when it comes to high gain distortion pedals. In many ways, the Metal Core is the spiritual successor to the mythical HM-2 from the 80s. Both offered grinding, saturated distortion tones perfect for metal styles. The ML-2 is slightly more tameable and lacks the fizzy edge that the HM-2 could reach when dimed so overall has more clarity. Even the controls and four knob layout is shared. There’s no reason why the ML-2 Metal Core can’t become just as legendary as its older counterpart with all the aggression and crushingly thick distortion you expect, just with greater clarity. A future classic.
