Tone control using Two NPN transistors (BC107)

Two NPN transistors (BC107) are used in this circuit tone control, this circuit is biased by 30 volt DC power supply, Audio input taken through the 2.2μfd capacitor and separated into two lines to control bass and treble effects, output from the tone control elements are fed into transistor pre amplifier, output is synchronized and then fed into the output pins here the output is taken from second transistor emitter terminal.
