Today I changed the 470k resistor to 2,2M and now it works. But just with my Tele and very hard picking. choosing higher values or even leaving the resistor out makes it more quacky, but also adds distortion (bad trans. distortion ;-)) Are there any other mods I can try? PS: I used RG Keens layout (that's why I'm a little bit disappointed, because his layouts always worked very well...) Thanks, Pete I built this some time ago, and it didn’t work (sound, but no quacking).
