hello.
the lm358 is a conventional ic,not really an audio ic................
you can try to use a typ. audio schematic where you swap the ic's to the lm358.
example:tone control

mjf showed you one in post #2

Almost any opamp data sheet has a tone control shown as an application... and any opamp will work.

Here's another, perfect for a TL072

Edit... actually the one in post #2 has an error... the opamp inputs are shown incorrectly (reversed).

The LM358 is a horrible excuse for an opamp. It has a class B output stage and slow speed, so it has big problems with crossover distortion. Even the much-reviled 4558 would be a better choice than the LM358.

I looked the LM358 up after your comment and I think you were being a bit generous. I think a tin can and string could come close to beating it.
