Hello Guenther,

I really like the German name for this circuit 😛

For the Lectron Baxandall proposed above, I used only the parts of the Basic and extension set, do I was a little bit bounded to the parts available. This is why I used a different circuit around the treble control. I made some measurements with a sweep oscillator and oscilloscope and it performs very well.

Don’t forget that there’s a lot of volume loss. This is why I used a preamplifier first !

Maybe you can try to build it first and compare it with the following proposed weblink.

I found a website where a Baxandall circuit is proposed using 2 potentiometers of 100K.

here is the link.

Maybe this is the circuit you were looking for. It uses an opamp as active component.

Using this circuit saves some time calculating it.

I believe that any opamp will do fine here.

I will try the circuit out tomorrow and publish my findings.

Many greetings
