These are considered the holy grail of delays . Super rare early version with 4 Panasonic MN3005. Only a few of these made before they ran out of the original microchip and they they had to substitute em with a different one. These pedals use the same microchip as the legendary big box memory man deluxe but they run at 9v, they have a lot more options, tap tempo and they are half the size. You can read about it and you’ll find a couple of really nice showcase video on YouTube . These hardly come up for sale
