Block DC voltage while letting AC (your guitar signal) pass. They are also the heart of Tone Stacks (Bass/Middle/Treble) by filtering specific frequencies.

Guitar Input -> 1M resistor to ground -> 0.022µF cap -> Grid of 12AX7 (pin 2) 12AX7 Cathode (pin 3) -> 1.5kΩ resistor + 25µF cap to ground 12AX7 Plate (pin 1) -> 100kΩ to B+ -> 0.022µF coupling cap -> Volume pot. guitar amplifier electronics basic theory pdf
