Hi there,
I am finally getting around to building a Serendipity v4 that had been sitting around. I am having some issues where the pedal was passing the signal through the circuit and having no effect on the sound. I get no effect from the pots and no drive. I know that the signal is somewhat attenuated by the sound coming out. I do have a true bypass when it is switched off. I have used an audio probe and am getting a signal throughout the circuit, but again, it is basically just a somewhat scratchy quieter version of the bypass signal. Also, I am not getting the LED to light up, but that may or may not be an issue of a broken LED (I do not have a replacement at the moment). I am wondering if the main issue would more likely be a grounding issue or an off board wiring issue. Thanks for your help.
No way to tell without more information. Voltages and a pic of the build/wiring are needed.
I understand that my post was lacking. Sorry, I will get more later. When I ground my DMM on the black line coming off of the battery (which is attached to the ring of the input jack...also, I do not have a wall wort for it right now to test with a different power source....I know- amateur) , I get 9 volts on the ground parts of the circuit. (Like pin 4 of the IC). When I connect the black line of the dmm on the ground wire coming off of the circuit which is attached to the other grounding lines of the circuit, I get no voltages. This does not seem correct to me. When I connect all of the grounds together, I get no action on the circuit, just bypass. When I am measuring voltage against the black line of the battery, almost everything on the circuit (both transistors, all of the pins on the IC) measure about 9 volts. I am getting the same voltage almost everywhere. I assume that this is a problem. Would this be a problem with the off board wiring? Sorry, I realize that a picture would help but I am work right now. Thanks.
Yeah there something going on with how you have things wired up. A pic showing the wiring would help a lot here.
