Thanks for reply psw! Sorry about that i don't gived much information, i try to fix this thing next time . You explained this all things very well! I have misunderstanded that i must connect driver to "left input", understanded now that it must be connect it to right output, what stupid i am... I tested right output with speaker and it's works! . When i testing with driver and hold it above strings it works (the strings will vibrate). I have much of humming? when not 9v battery connected/unconnected, tried to ground circuit to guitar but not helped. Especially when i go amp and crank more drive up the voice will more humming in this circuit. When i tested with clean tone i don't have much of humming but when i choose my line6 preset then it is very loud? This must be somekind wiring or ground problem in (this) circuit, i don't understand i have thousand times checked that everything is connected to right, strange. I don't have this kind of ground problems wihtout circuit. Did i have connect Bridge mic and amp jack to left input in circuit?.

Hello! I still can't get my sustainer work, here it is . I'm out of answers... picture link: http://www.timelessfields.com/test.jpg

Thanks PSW! for your fullness answer, you gived me new hope for this project. Yes i tried to layot pcb myself, but i getting "blinded" for my own errors . I will check this all things out and try to build it again with new components.I try that LM386 with x200 extra cap and resistor if it work someway, getting more stable signal. It's a great to see such wise knowledge of things here! Keep going!

Hello all! I tried to drawing this layout: But i can't get it work, it humming and etc problems. Can anyone check this out, if it drawed correct? If somebody got working fetzer / ruby sustainer pcb/component layout, please send it to me. I tried to build DIY FEVER fetzer-ruby, but it not work. I don't understand why the are two ground points, and why it is humming when not batteries on. I winded my mic 9ohm. THX ALL!

Hello! I have some problem with fetzer/ruby and don't know some things. I use Diy fever Fetzer/Ruby circuit diagram but don't understand these: 1. Why the are two ground in circuit? 2. Where i put battery ground, to the circuit ground? 3. I have loud awful voice when not batterien on. 4. i don't understand which one is Transistor J201 source and drive? i know where is gate. Source goes 1M? and drive goes condensator?and trimmer. 5. Is it problem if i have 9ohm mic winded? Help me, i know u understand. -Ari, finland.
