Like new Fender MTG Tube Distortion pedal along with original box and all box contents. Board ready with clean velcro on bottom. Full tested works perfectly. Rather than trying to replicate the complex behavior of vacuum tube breakup digitally or with transistors, Fender chose to build a pedal around the real thing. At the absolute center of the MTG Tube Distortion is a genuine, US-made New Old Stock (NOS) 6205 subminiature preamp tube. This original circuit, designed in collaboration with legendary amplifier guru Bruce Egnater, functions essentially as a tube preamp inside a compact enclosure, running an internal switch-mode power supply that converts the incoming 9V power up to 150 volts to properly cook the tube's plates.
