I'm sorry it did not catch the equalizer
my computer is working in the garage (lol) at a distance of almost a kilometer from my house.
and the street is now minus 22 degrees Celsius, do not want to go out in such cold =)

You did a great job :thumbsup , it is necessary to choose the denomination capacitors =)

No, I did not get a chance to get a smd tester to measure the capacitors.
The pedal is no longer in my hands, I did everything possible :(

in fact, it's not scary, because a three-band equalizer in JHS is not really good, it's easier to pick your own)

The mid pot was very very good, the bass pot too but not the big thing. The high control was very bad but still work well (It was very extreme, perhaps a very personal impression)

All the luxury of this pedal versus the V2 is the control of mids

Some capacitor values may apply in comparison with the Three Band Activ Tone Control of the EQD-Talons.

How calculate frequency response for bass mid and treble?
Treble part looks not full

Hello everyone!

I tried the last scheme on the breadboard, I'll leave my experience here.

Well treble and mid ran. The mid was what worked the best. The treble acted more like a presence I do not know well. He himself with the maximum potentiometer was not sharpened in several configurations that I tried. The bass did not hear any difference.

I changed some cap to the bass and still do not know what's wrong.

:shock:
