What kind of distortion does the LM386 produce?
The “distortion” the LM386 is producing is “clipped” distortion, and probably looks something like this if the output were viewed: That is a “hard” clipping at the tops and bottoms, and we perceive that as a “metal” type of tone.
How is the gain of an LM386 amplifier adjustable?
The gain may be simply made adjustable by connecting a pot in series with the above explained capacitor across the pin 1 and 8. The following figure shows a typical IC LM386 amplifier circuit having the bare minimum number of components required to make the IC operate at its internally set level of gain 20.
Why does LM386 do not like diodes after a signal?
Lm386 does not like diodes after its signal, particularly because it will clip on INPUT before any amplification will occur. This is why gain is achieved via a simple capacitor between pins 1 and 8 and a pot controlling the INPUT level as opposed to controlling resistance against that capacitor.
Where is the 10 ohm resistor on a LM386 AMP?
Take signal in one side, ground the other, and the middle lug is your output lead. You can get away with losing the 10 ohm resistor but you’ll be loading the pot. To have your LM386 amp clean, don’t put anything between pins 1 and 8, nothing, zero.
What are the features of a LM386 low voltage power amplifier?

Is the LM386 rated for high power?
Give the number of obviously wrong things in your diagram, it would be difficult to guess what could be improved in the gain and tone control areas. The LM386 is not rated for high power.
