Since it appears under a E7 I can only surmise that it means use the counter-bass under the G# if this is for a 120 bass accordion.
Thanks for the reply. I have seen other sheets with notes in parentheses (). Based on the explanation I can find, it means notes that are out of the ordinary, and it should be played as it is---if you can, and it can be ignored or skipped---if it's too
difficult for you to reach. I suppose the Russian letter, в, means the same thing.

It could mean a counter bass because that might be easier to reach in
the context of the bass progression. Otherwise you would use the B. You
have an augmented 7th with the C unless there are are 4 note basses,
e.g. if the 5th has been removed in the modern bass system the E G# and
C would not clash with the B in the 4-note bass system.
Thank you. It's great that there can be these sensible options.
