This is Brian.
He is a buffer
He is also super tiny (10x14mm)
You can use him as a standalone buffer or to add buffered bypass to all of your pedals.
You can also use him for all kinds of different routing options like splitters, mixers etc. (check the build docs for a few ideas)
He's also a great opportunity to try some SMD soldering.
It is really not hard
Just watch a youtube tutorial first and you will be good to go
Build Docs coming one day
