Point of reference: this is a Baxandall tone control. You will find similar schematics all over the net. Most include an input buffer or output to compensate for the negative gain. But with a powerful amp, not necessary.

It does mean you are going to crank the volume louder. So you need to be extra careful about noise getting into your signal. Ideally you'd put this into the same box as the amp, removing the last set of interconnects.

Thanks for the input, of all of my projects, I still use this one every day. I have it connected to a Radio Shack switchbox, then to a Magnavox 180 series tube amp. Gives me quick and easy control of sound.

Welcome to the forum!

[so on the negative on the input is also connected to the negative on the power supply on the active tone control circuit does that cause a problem that the negative from the source input goes to a sound card negative from a computer sound card source which is also hooked up to the negative from the input source which is a small 12 volt dc power supply would this not cause hum?????or are all active tone controls wired up this way????
