Boss ML-2

Metal Core Pedal

This is the most aggressive distorter that BOSS has ever built - for the hard core of metal fans! The most extreme distortion with a snappy attack for the hardest riffs!

When the most brutal of sounds are desired, the ML-2 Metal Core is the perfect weapon: for death metal, industrial, grind core, extreme metal, etc.

The bass control of the LOW knob ensures extreme bass, even for 7-string guitars and drop tunings, while the HIGH knob ensures cutting, metallic highs. Ultra fierce!

  • Ultra heavy distortion - ideal for the hardest riffs
  • Also for 7-string and dropped tunings
  • LOW knob for extreme bass (7-string guitar/drop tunings)
  • HIGH knob for cutting treble
  • Robustly manufactured - typical of BOSS
  • Weight: 0.4 kg
  • Dimensions (W x D x H): 73 x 129 x 59 mm

A pedal that has what it promises.

Dödelbert, 15.10.2009
Operation & processing

Simple, intuitive operation with four rotary knobs:
"Level" controls the total volume of the effect. "Low" and "High" reduce or increase the amount of low or high frequencies in the sound, which, of course, can not affect them. No. 4 controls the distortion. Wonderful solid metal construction; No wiggling knapples, or the like. The potis can also be turned softly, but not too easily, that they were unintentionally adjusted. It is as if you could easily slice slices without impairing functionality.


In the most important criterion I give 5/5 stars. A distortion pedal should distort. This is exactly what it does, and not too tightly. Even with the minimum setting of the controller, it delivers overdrive, at maximum - there is actually extreme gain, which is more likely in the Grindcoresektion is in demand. More does not work and would be silly. At least one has enough reserves, for all cases;)
So perfect for genres like: Death / Black Metal, Metalcore, Trash, etc. Differentiation of the sounds below (no muddy, blurred sound), and the practically nonexistent noise I evaluate, even with maximum distortion as very good, whereby I with here A 40 euro distortion pedal of a fairly well-known brand that I once owned. This way I can use the pedal with my old 80-watt Valvestate-Amp (whose loudspeaker can be overdriven by the pedal with the greatest distortion) even in the 1st Overdrive channel, which me
Setting options.

"Miracles" are not to be expected from the "low" and "high" controls, but this allows the sound to be refined, which is quite sufficient for me. That makes the amplifier anyway.


All in all, a pedal, where not only the gain fetishists among us will have real joy. Personally I absolutely can not fault anything and am completely satisfied. The only downside I see is only the slightly steep price. However, this will only follow the guiding principle that quality has its price. I am in any case very satisfied :)
