I recently used a stomp with 2 108's in a garage practice and 108's sounded great at reasonable sound bass & drummer.
I had plenty of volume left over but didn't need it. I did have the b3 organ synth going in the return of the stomp and out to the 108's and it was very nice.
They are easy to load and I have used them on loud stage when running sound too, I threw one up at ear level, near the sax player, and another time pointed at the B3 player and they were happy - it was a quick easy fix.
Also the bass push button is not needed for what I do, gets too muddy.
Whatever I do, the stomp & the 108's were always with me even if just as backup
& I would often just run the organ synth through the 108's in stereo as a stage monitor
