Op-amp based Treble Boosting Circuit

Though a simple circuit at its core, I'm very proud of the Treble Boost circuit I designed using a single op-amp, in fact the simplicity is one of the things I'm most proud of. Using a simple R-C filter with a potentiometer this circuit adjusts signal level on the user input of the potentiometer and according to the frequency as dictated by the capacitor. This tested very well (nearly perfectly), and is a good example of my creativity combined with electrical knowledge.
