Base pedal set all wrong (8)
I believe the answer is:
pedestal
'base' is the definition.
(synonyms)
'pedal set all wrong' is the wordplay.
'all wrong' is an anagram indicator.
'pedal'+'set'='pedalset'
'pedalset' with letters rearranged gives 'PEDESTAL'.
(Other definitions for pedestal that I've seen before include "Support for bust" , "Statue's support" , "Statue's base" , "Plinth, base" , "Support or foundation" .)
