Input Conditioning Op-Amp of pedalshield

I found this circuit for conditioning the signal for the PedalShield Uno(Guitar Effect Pedal made using Arduino). I am trying to make a similar project and I copied the circuit but the Op-Amp that I have bought (only one available) is AD8051. The one on the circuit is supposed to be TL972.
AD8051 datasheet
I have no understanding of these matters and I would very much appreciate if you can point out the different parts of this circuit and its functionalities. I only know the first part before the op-amp are low-pass filters. I would like to understand this circuit so I can make my own for the AD8051 or if I can avail the TL061.
I have tried compared the datasheets but I don't understand a single thing. We are taught only on the software area.

I'm sorry but I don't have the background knowledge for these stuff. Helps in making my future questions better.
