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.

so, in case someone is interested, here's the final schematic and layout. simple buffer, booster and splitter. this is the first pedal in my chain =)
