I would say your guitar could provide all the power and volume needed. I play pretty hard, not sure how hard that is relative to your playing style. In jams, it’s hard to sacrifice control and technique for volume, but having everyone else hear you is important too. I would work on increasing your pick striking power gradually, keeping your technique good and not overplaying. The other pickers can adjust their attack as well when you take a break in order to hear you better.
As you practice at home, try to play with more power and build it up, you will like the results in tone of your guitar and the volume will improve at the jams.
Hope that helps,
