Like a bass (3)
I believe the answer is:
low
'like a bass' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for low that I've seen before include "Deep sound of cattle - not high" , "SECOND PART OF 14" , "Dejected; moo" , "Make a cow-like noise" , "Depressed; moo" .)
