hello,
i was looking for a simple buffer/boost and i did this. in spice it looks good, but i don't have my breadboard at this moment and i read somewhere that the switch could make a pop noise... is this schematic ok or do i need some improvement?

edit: i think this post should be in the workbench section. sorry

It probably would pop since for a few ms the feedback would be floating. Solution is to simply short the pot for buffer mode. I.e. just use a SPST, excluding pin 1 of the depicted switch and connecting the pot at pin 2.
