Which buffer solution for guitar pedal?

Building a Daisy based pedal for a friend. Guitar pedals are new to me, more used to dual rail systems and plenty of input voltage. I´ve looked at both the Daisy Petal (rev 5) and Terrarium schematics for input/output buffers. Any suggestions which to prefer?
Is there any point in amplifying the input to the Daisy Seed, considering the average guitar output being far from the input limitations of the Daisy?
