How cum, errr why did that schematic post so BIG?
Hey John,
I am sorry to pick at your project with the LM386, and I am sorry that I mistakenly said that it has bass-boost (it doesn't).
In addition to your 0.1uF cap (C7) at its input to ground that attenuates medium and high audio frequencies when your volume control is at half-resistance, according to the datasheet your 10uF cap (C3) at pins 1 and 8 has backwards polarity!
Here is the LM386 part of the schematic that you posted and I hope that it isn't too big:
