It features deep low frequency, straightforward sound, wild distortion. When we Input a guitar with twin coil pick ups it gave us the name, the Mjolnir promises to become a companion walking into metal world.

We took the name from Norse mythology, Mjölnir ( try pronouncing it MY-OL-Neer; or Mjolnir, Mjollnir, Mjölner, Mjølner, Mjølnir or Mjølne. Anyway, it is the hammer of Thor, a major Norse god associated with thunder. Mjölnir is depicted in Norse mythology as one of the most fearsome weapons, capable of leveling mountains. In his account of Norse mythology, Snorri Sturluson relates how the hammer was made by dwarves, and how its characteristically short handle was due to a mishap during its manufacture.

Although no dwarves have been involved in its design, the JOYO MJOLNIR amp impressed us greatly at the Shanghai Prolight and Sound Music Show, showcased as a new product for 2015.
