I'd like to add a simple op amp-based tone control circuit to my preamp for
desktop speakers& sub that I'm modifying from stock.

This is the simplest I found:

(I have +/- supplies so I will be eliminating all coupling caps and changing
Vcc/2 to ground.)

What are the positives and negatives to this design?

Better circuit (yet simple)?

Thanks.



This is the classic Baxandall tone control.
There is plenty of material if Googling for
'baxandall'.
