Bought this little amp from ebay and it works great amplifying my portable mp3 player.

It's a variation of the circuit featured in the datasheet, as it includes C1, C2 and R1.

1) What is the purpose of C1, C2 and R1, filtering?
2) How can I convert it to amplify my guitar's signal and use headphones as output? (maybe also use an fx pedal between the guitar and amp)
