Checked with a Scottish friend on this - she confirms it's "ay", as in "hay," "day," "lay" etc. posted by badgermushroomSNAKE at 9:21 PM on October 25, 2012
I asked my academic supervisor, who is Scottish and a phonetician. Here are some fun facts about Ae:
In his words: "Yon's pronoonced [e:] gin ye're frae roond thae pairts, i.e., just like the name of the first letter of the alphabet."
The Forest of Ae is known as a centre for mountain biking.
Ae is the shortest placename in Britain.
Lastly, 'ae' is one spelling of the indefinite article in Scots, as is Robert Burns' poem 'Ae Fond Kiss'.
