Welcome, you are looking at a great piece.
This is the Vintage 1983 Ibanez AD-9 Analog Delay Effects Pedal.
This MIJ Ibanez AD-9 is one of the most sought after delay pedals every made.
The super clean delay has a maximum time of 300ms, with control over repeats and delay level.
This AD9 is in very good overall condition, especially for its age.
Tested and works as it should.
These Ibanez/Maxon pedals are becoming harder and harder to come by as time goes on, especially those fully working and ready to add to your pedalboard.
Don't pass this by.
