The -D4 is a straight-up distortion pedal.

Just a good distortion pedal that has plenty of volume and gravelly gain on tap with a true tone that will boost or lower highs. At high gain it can get a little muffy, at lower gain it is looser and can work as an overdrive with a bit of chest hair on it or even tap into rodent (PROCO RAT) territory. Hitting a hot tube amp with the -D4 gives it some serious \m/etal vibes, almost like a JCM 800.

Smaller 4.37″ X 2.37″ X 1.07″ MXR sized enclosure, true bypass switching, common 9v center negative BOSS style power input and battery snap. Power supply not included.
