Custom 2in 2out router

[pufferton]

So I'm looking to build a custom router but need help getting started.

I want to have 2in (plug a guitar and mic) that I can switch between and send a constant out to two jacks (pedal board and the other to tuner)

IF POSSIBLE I would love to put a buffer in there since it would be my first pedal in my chain.

I only need one LED and one switch and four jacks. Nothing fancy.

Any help or schematics to point me in the right direction?

Thanks!!

Passive A/B (search), preferably make sure the unused source is grounded, into 1:1 buffer (TL071), split to tuner and output, should do the trick. There's many ways to do this but that's the most straight forward.

im re-looking at this comment before i build. does it matter if i buffer first and then split or split and buffer my main out?

i ask because of possible signal degrade from splitting...
