Bit of a beginner question - can someone please help me with the filter circuit in the attached schematic? It's a tone control / switch on a guitar pedal. I know what it sounds like - which is a tight band pass or high pass filter removing a lot of low frequencies.

Questions
- why are there resistors and capacitors in parallel? is the pre emphasis?
- why are there two of these in series? is this a second order filter?
