Here we have a cool-looking vintage DOD Electronics Stereo Phaser FX20-B guitar effects pedal from the 1980s. This pedal would make a perfect addition to your pedal board. The pedal was created to give your guitar a cool distortion effect and was seen as high-tech during that time. The pedal can be powered by a 10V power supply or a battery. 

The pedal looks to be in well-loved condition, with lots of scuffs and scratches here and there. The input hookups have some light surface rust on them. There is some tape on the front and sides of the pedal. I have not tested the pedal since I lack the correct power supply. Please see all the pictures to determine the condition. 

Overall, this pedal would make a great addition to your collection. This item is being sold as is, as found, and as untested. Thank you!
