As a pro bassist, I started getting asked to double on acoustic guitar, and ukulele occasionally. I was able to work for artist in particular for a very long period of time, and seamlessly switch from bass to acoustic.
I used the PA sometimes, other times I used a bass amp. It was always smooth. Nothing fancy, but it works as it should.
Click it for bass, click the other channel for acoustic. The colored lights tell you what channel you’re in. Again, it’s simple, takes up zero room, you can tape it the top of your amp and loop the cable through your amp handle.
It works to use two amps also if you prefer it to switch rigs, not instruments. Quiet, effective and nice weight, heavy construction
