It was just caused by misbiased..
(I set 0.5v instead 5v. . .)

Hi Gurus,

Now I'm building below stompbox and there's problem.

https://www.dropbox.com/s/kprzfd7uzo7iqvu/aion-plasma-colorsound-overdriver-documentation.pdf?dl=1

Firstly it doesn't output any sound when effect: on.
So I try to trace the audio and have some question.

- I connect the output cable after the Q1's 
emmiter or collector. There's sound but the loudness is almost same as dry output. working correctly?

- Q1's collector bias is around 1v. Aion wrote it should be 2-3v. shoul I decrease the value of R2?

- After Q2 collector there is sound but still not loud.

- After Q3 collector. . . no sound lol.

I checked electrycal caps and transistor and seems they work properly.

Any advice really appreciate.
