Hi all,

I have a circuit where I have a TL072 set as a unity buffer and as a pre amp for my electric guitar

Which feeds into an LM386, and an 8ohm speaker
When playing with the humbuckers, the audio quality is good without clipping

But whenever I switch to the single-coil pickups, the audio starts to ditsort

I want to reduce the gain of the lm386 further below 20 such that it does not distort my single coil pickups

When I add a resistor across pins 1 and 8, it simply increases the gain.
What can I do to decrease it??

So what is so difficult about adding a potentiometer to the input of the LM386? A volume control is the usual way to control the gain of an amplifier.

 

If you go to YouTube and type in 386 Done Right, there is an excellent video done by John Audio Tech. This guy knows how to make the LM386 perform like a champ. I have attached a screenshot, so you know which video it is. I hope this helps you.
