Pin 1 is power ( datasheet recommends a 100uf power filter cap. Pin 2 is the output (through a 470uf cap). Pin 3 is for standby which isn’t needed in a guitar amp so can be left unconnected and Pin 4 is input ( through a 10nf cap). Pins 5,7 & 8 are not connected and  Pin 6 plus pins 9-16 all go to ground (datasheet recommends connecting pins 9-16 to a heat sink). Thats it, 1 chip 3 caps and you have a decent sounding working amplifier, even without adding a buffer or booster.
