Hi!
What do people use to implement Tone (Treble, Bass), Volume, and Balance Control? I'll list the ones I'm aware of - hoping that someone else has some great alternative suggestions for DIY!
I mean, there's the OpAmp+Baxandall approach but it's very component intensive - especially in Stereo.
Then there's the old LM1036/TDA1524 ICs - which had great usability and only needed single gang pots. But the SNR/THD was not too great, and they are anyway retired from sales.
There's the TDA7440 - which perhaps doesn't have great THDN but does the job. Downside is it needs an MCU for the digital control. And perhaps the NJW1119A - which doesn't seem to be purchasable from any of the regular channels.
Then there's of course the full-blown DSPs, but that's perhaps a bit on the far side...

Baxandall's are in various more or less complex/accurate versions. On the other hand, in my germanium head amp I use a single pot high-low tone control. Volume and balance are always two pots (vol & bal or twin vol) or skip the balance if you're sure (or hide it on the back or inside).
