One has a record or disc with loud guitar (8)
I believe the answer is:
offender
'one has a record' is the definition.
(criminal record)
'disc with loud guitar' is the wordplay.
'disc' becomes 'O' (disc-shaped letter).
'with' says to put letters next to each other.
'loud' becomes 'f' (short for forte - 'loud' in music).
'guitar' becomes 'fender' (famous guitar manufacturer).
'o'+'f'+'fender'='OFFENDER'
'or' acts as a link.
(Other definitions for offender that I've seen before include "One breaking rule" , "Wrongdoer" , "Committer of illegal act" , "Culprit" , "Transgressor, lawbreaker" .)
