This is One of two Pedals that I received when I purchased my ARP Avatar new in 1977.
The other Pedal has been sold.
I used this Pedal primarily to turn the Avatar on and off in a live situation though It could be used to engage the portamento in a live situation, as well other functions also.
This Pedal always worked properly, never had one second of problems with It.
These Pedals can do more than one operation as Avatar owners are aware.
Please look at all pictures closely and ask any questions I may have left out.
The pictures constitute the majority of the description for this item.
Thank You!
