Try wiring the 386 the conventional way, as shown in the datasheet :-. Change the 100k input pot to a lower value (e.g. 10k) and remove the 10nF cap on pin 3 of the 386, to reduce signal attenuation. Re-think the pre-amp. The way it is biased will probably result in clipping of positive-going parts of the signal.

The integrated chip LM386 is a low power audio frequency amplifier requiring a low level power supply (most often batteries). It comes in an 8-pin mini-DIP package. The IC is designed to deliver a voltage amplification of 20 without external add-on parts. But this voltage gain can be raised up to 200 (Vu = 200) by adding external parts.
