For the past year I've been running a very basic pot still. Getting good results and learning more every batch I make. The still (as I mentioned) is very basic: 6 gallon boiler, 1/2 gallon slobber box, and a condenser. I am currently redesigning the still and adding a 2.5 gallon copper thumper. I am not sure if I want to keep the slobber box on the still now that I'm adding the thumper. Is there any point? I've not been able to find anybody on this site running a pot still with both a slobber box AND thumper so I'm kind of guessing it's pointless.
Probably don't need the slobber box anymore. During stripping runs you can leave the thumper empty and use it for a slobber box. If you have more wash than will fit in the pot, you can put some of it into the thumper. Just don't get carried away and make the thumper puke.
Slobber box pretty old school.... slobber box in the line up for your newly commissioned helper,,, while yer away......slobber box a loss mitigation tool. slobber box for a fire. Slobber box for a dead line....slobber box ain't helpin make better likker . slobber box keep ya from gettin dismissed if ya fall asleep "at the wheel".
If you go way back there was no difference between a slobber box and a thumper. A slobber box was nothing more than a thumper charged with water that was designed to prevent any foam or puke getting into the worm condenser and blocking it. The more common configuration of the slobber box that we see these days evolved later.
So long as you accept that they do 2 different jobs, then there is no harm in putting a slobber box right before your worm. Whether you need it or not depends on what condenser you have, what you run and how hard you run. Think of it as a safety device.
