|Tiago||Mark Hammer´s Dr. Quack|
I just finished the Dr. Quack from the projects page
here in Ampage site, but no sound. I ask Mark Hammer, that I know that build one and could
answer, if you make this project with the layout or the schematic. I made with the layout and there´s a couple of things different from the schematic. There´s sound, but is too low and no wah. I used polyester caps and a TL072. I put a jumper instead the resistor 10 ohms that goes to +9v, and a pot of 20K instead the trimpot. When I plug the battery, only one
LED light. The other stay off. There´s no difference in sound when I move the pots.
If anyone can help me, ´cos WANT get this thing work.
