I believe the answer is:

first offender

I'm a little stuck... Click here to teach me more about this clue!

'person just getting a record?' is the definition.
I can't tell whether this defines the answer.

'jazzy riffs absorbing to guitar' is the wordplay.
'jazzy' indicates an anagram.
'absorbing' indicates putting letters inside.
'guitar' becomes 'fender' (famous guitar manufacturer).
'riffs' anagrammed gives 'firsf'.
'firsf' enclosing 'to' is 'firstof'.
'firstof'+'fender'='FIRST OFFENDER'

Can you help me to learn more?

(Other definitions for first offender that I've seen before include "One acquiring conviction" , "Novice in crime?" , "One committing crime on initial occasion" , "one that hasn't gone wrong before" , "One without 'form'" .)
