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

'instrument controls' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe you can see an association between them that I can't see?

'gas blasted with protons' is the wordplay.
'blasted with' indicates an anagram.
'gas' anagrammed with 'protons' makes 'ORGAN STOPS'.

Can you help me to learn more?
