UK pubs are cosy, no PA.
Band will probably be using a cheap vocal only setup which everyone will have to stay under.
On paper there is nothing wrong with the combo you have. I suspect it is far overrated. I played on the 115 version, underwhelming but probably sufficient for your venues.
If you put it up on a chair you'll get a better appreciation for the sound going out into the room. Don't be fooled by apparent loss of low end, it's actually the mids and highs reaching your ears in more accurate proportion than when they were aimed at your knees.
EDIT, missed the post about the crackling, indictates lack of available volume.
