Try Googling for 1) tutorials on basic electronics to get an understanding of the function of the parts, and 2) the operation of bass boost circuits.
As for drawing block diagrams, any software for graphics or creating presentations (Powerpoint, etc) should suffice.
 
audio amplifier with bass boost to you too. Here is a battery powered MP3 player booster I designed some years ago. It was designed to attach to PC loudspeakers that nominally have a 1k input impedance

Transistors Q1,Q3 and Q2,Q4 are Sziklai pairs that add current capability to your
op amp (operational amplifier) IC1.
C6,C7,C8,R5,R6,R7,R8,P2 is the feedback, which is also responsible for bass boost.
Essentially this amplifier amplifies bass more then
it amplifies higher frequencies.

I would consider the op amp as a preamp and the transistors as the power amp. With the bass boost feed back on the bottom.
