Vintage 1970's Univox FL-1000 Flanger-Delay Guitar Effect Pedal

This listing is for a Vintage 1970's Univox FL-1000 Flanger-Delay Electric Guitar Effect Pedal. This pedal was made in Japan by Univox in the 1970's. I am not sure if the pedal is working correctly or not. The Flanger works and sounds amazing. The delay has almost no effect and may not be working. I did some checking online and it seems to be a common problem with these so it maybe just how the pedal was made but please be advised the pedal doesn't really have any delay sound. If you are looking for a very cool Flanger this is a cool pedal to buy but if you are looking for a delay you should buy something else. The pedal shows cosmetic wear and also has some holes in the side, the reason for I don't know, it was like that when I got it. Again, it maybe that the pedal needs repair and I am selling this pedal AS-IS because of the issue with the delay. Please look at the pictures and email with questions.
Thanks for looking,,,
