Default Korg nutube 6p1 tube buffer/harmonizer

After playing around with the 6P1 tube, my son ask me to build a universal purpose box with it.

He likes the sound of the Korg SV-1 and Vox MV50 guitar amps. Further he often uses tube buffers to let clean equipment sound like tube amps.

The tube buffer/harmonizer i like to make has adjustable harmonic distorsion from almost nothing(0,12%) to 10%. Input sensitivity from 5mV to 4V. balanced and unbalanced input and output.

Below the PCB which I shall build.
