The MXR M-104 Distortion Plus (Distortion +) has been around since the 70's and is known to be the signature sound of Randy Rhoads.
The word distortion makes us, guitar players think immediately about that heavy distorted sound. However the Distortion Plus is known for it's mild side. Actually, when you set the distortion knob to minimum and the output to maximum, the Distortion Plus will drive your amp nicely. On the other side with the distortion set to maximum it will deliver that distortion-fuzz sound it's famous for.
The MXR Distortion Plus pedal is germanium powered and feels very 'vintage', powered by a power supply or a 9 volt battery, it's darn simple and that is great!
