Extremely sublime opening pitches shock producers (6)
I believe the answer is:
tasers
'shock producers' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'extremely sublime opening pitches' is the wordplay.
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'opening' means one lot of letters goes inside another (some letters open a gap in others).
'pitches' becomes 'tars' ('tar' can be a synonym of 'pitch').
'sublime' with its centre taken out is 'se'.
'se' placed into 'tars' is 'TASERS'.
Can you help me to learn more?
(Other definitions for tasers that I've seen before include "Stun guns" , "Paralysing arms" .)
