I have owned this delay unit since i was in my early twenties from  new i am now 60 lol! I had it in the loft  for for a few years but has been sitting in various cupboards around the home wrapped up from dust for a numbef of years. When plugged in the light comes on so there should be no problem of it working but i havent got an amp to try it out.

If you buy it and it happens to not  work just return the  item and you will be fuly refunded on receipt, i doubt very much it  wont work i remember digging if out and  using it with my son 5 or six years ago.

See photos for casing wear over the years. It is Vintage....oh its still has the same plug on it from new lol!
