tremolo

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

'musical effect' is the definition.
(I've seen this before)

'us band in toledo removing editor's' is the wordplay.
'us band' becomes 'rem' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'removing' is a deletion indicator.
'editor' becomes 'ed'.
'toledo' with 'ed' removed is 'tolo'.
'rem' going within 'tolo' is 'TREMOLO'.

Can you help me to learn more?
