Analog Chorus similar to Boss CH-1, but with the Tone circuit located before the BBD

The build process went smoothly, no issue to calibrate the modulation by ear.

I compared it with other chorus circuits, and i find the SCH-1 closer to the CH-1.

Only downside is that the original SCH-1 is stereo, this build has only one mono output.
Its surely possible to modify this build to get two outputs, but i didnt try that yet.

The modulated sound is very pleasing, and we have some good range with all controls.
It can be deep enough, it can be fast or slow enough, and the tone control has more impact on the modulation than on a CH-1.
For example, we can cut lots of highs in the modulated signal and get some darker curves. It can also do the opposite and be very sharp and bright.

Great chorus with lots of flexibility.
