Live sound question - swapping guitars / volume

Hi folks!

I have traditionally been a 1-guitar-at-a-time guy live. My current main is a MIJ Traditional 60s Jazzmaster, but some of the songs in my band benefit from the use of my SG instead.

SO here's the question - in a live setting onstage, swapping between the 2 can result in a significant volume difference. How do other guitarists handle that in a club / small venue situation without burdening the already-probably-over-it sound person? Is this a "warn them before, play both during sound check and move on" thing, or am I overthinking it?
