This is a vintage 1980 Ibanez Analog Delay AD-80 guitar effects pedal. This very rare version features; the highly coveted MN3005 chip, the early production skinny “bud” box and an 18v power supply requirement. This first generation AD-80 is sonically superior to those which came afterward, and the MN3005 chip is the preferred chip in Boss DM-2s, Electro Harmonix Memory Man delays, and all vintage analog delays. Produced in fairly limited quantities with respect to the abundance of the large-box varieties, this particular version has become quite rare and highly sought after. This pedal is in very good all original condition. It works great and sounds fantastic.
