City guides, by the sound of it (5)
I believe the answer is:
leeds
'city' is the definition.
(city in England)
'guides by the sound of it' is the wordplay.
'guides' becomes 'leads' ('lead' can be a synonym of 'guide').
'by the sound of it' shows a homophone (sound like).
'leads' is a homophone of 'LEEDS'.
(Other definitions for leeds that I've seen before include "West Yorkshire city" , "Soccer team" , "English city" , "British city and premier division football club" , "City near Bradford" .)
