The OP-AMP can be any single small noise op-amp, the original NE5534 is used. The 2N44 is probably to get replaced by other PNP germanium transistors without having much change in sound. The switching factor has been omitted from this diagram, but you almost certainly wish to add a bypass of some varieties to this impact.
This emphasis switch chooses a tone taste, this may very well be expanded to incorporate a wider scale of frequencies, but too tiny a capacitor value could lead to oscillation.
All tame a company internal confirmation of this impact has long been omitted, nevertheless it can be easy to add. This could be noisy, according to the platform, to ensure the capacitor with value 10-15pF may very well be positioned inside a cycle of OP-amp if you're apprehensive an excessive amount of squeaking.

About Audio Amplifier
An audio amplifier is an electronic amplifier that amplifies low-power audio signals (signals composed primarily of frequencies between 20 - 20 000 Hz, the human range of hearing) to a level suitable for driving loudspeakers and is the final stage in a typical audio playback chain.
The preceding stages in such a chain are low power audio amplifiers which perform tasks like pre-amplification, equalization, tone control, mixing/effects, or audio sources like record players, CD players, and cassette players. Most audio amplifiers require these low-level inputs to adhere to line levels.
While the input signal to an audio amplifier may measure only a few hundred microwatts, its output may be tens, hundreds, or thousands of watts. More explanation about power audio amplifier can be found at wikipedia.org

This is a video tutorial about how to a very simple audio amplifier based on the LM386 amplifier chip. It can be built for less than $20 (or might be less than $8 in some countries) and used to amplify any low level audio signal including a guitar, bass or mp3 player.
