Was glitchy volume increased on a good day? (9)

Ross

I believe the answer is:

hiccupped

'was glitchy' is the definition.

'volume increased on a good day?' is the wordplay.
'volume' becomes 'cc'.
'increased' becomes 'upped' (upping is a kind of increasing**).
'on' is a charade indicator (letters next to each other).
'a good day?' becomes 'hi'.
'cc'+'upped'='ccupped'
'ccupped' after 'hi' is 'HICCUPPED'.

I've seen this clue in The Times.
