The Arion MDI-2 Bass Distortion is a bass guitar effects pedal designed for dirty-sweet distortion. It features individual level controls for dry and distorted outputs, tone and distortion level adjustments, and a direct distortion mix control to retain natural bass frequencies. This bass distortion pedal offers easy 9-volt operation. The MDI-2 allows bassists to achieve a distorted tone without sacrificing their natural booming bass sound, similar to other distortion pedals like the ProCo RAT or Ibanez Tube Screamer but tailored for the low end.
