I am a newbie here
Question: How to calculate capacitators for changing freq of tone controls.
And searching for some way to build a nice preamp for double bass.
I have a jfet high impedance input
Also planning to use ICEPOWER as power amp.
But now the in between. Thinking about a chip amplifier TDA7440 or better, so I can control the amp with arduino or otherwise.
Now I want to change the control of the treble + bass controls. THere is a formula for that. But that is above my possibilities, so perhaps there are some examples, calculators etc. to work with. Other tips also welcome.

The formulas for the bass section look a bit scary but ultimately I think all you have control over are the turnover frequencies, in other words at what point in the spectrum the controls operate.
I would say trial and error might be as good as anything, at least to gauge the effect and how it actually sounds in the real world.
