How do you say FABO?

Seems to me that both vowels can't be "long", can they?
If the O is long, the A needs to be short.
If you make the A short, then the O can be long.
Otherwise "FABO and "FABOW" could be the same word.
Of course we are discussing a language in which read is read and lead is lead.

"Fay Bo" would be two long vowal sounds. remember the long "A" sound, is the same as the name of the letter "A". As used in the word "fame"

"fab Oh, is a short "A', and a long "O" . Here the "A is pronounced as it is in "fabulous" "fabricate", or as in the abbreviated word "Abs" (stomach muscles). lol
