Ok, this is a 2 part question.

So you wake up and Dylan is standing in your living room and wants to lay down some tracks - no fuss.

First scenario:
Just him and his acoustic guitar - the acoustics in room are what they are - he wants both vocals and guit recorded together same time. No fuss.
What mic, gear, setup would you use? Let's say on a low-medium budget.

Second scenario:
He brought a guitarist - which can be elsewhere in the apartment - but they want to record together at same time as well.
What mic, gear, setup would you us? Same budget.

Many thanks to all for playing along!
