I recently built a guitar effects pedal. On this occasion, I wanted to try my hand at making a pcb instead of using perf board. I also decided to forego bread boarding the circuit as it has been built by many people since it is a very popular design. After completing the build, it would not work. After much troubleshooting and internet research, I found that the issue was that the trim pot was letting full voltage get to the jfet. It read 8.4 volts on all three pins. Of course, I removed the pot and it tested fine. I ended up getting the effect to work by installing the pot as a voltage divider. Pin 1 to ground. Pin 2 to the Drain of the FET. Pin 3 to voltage.
Am I misunderstanding how the pot is connected in the schematic? Is there something else I doing wrong and using a voltage divider is just creating a work around?
I have attached images of the original, my schematic, and my layout. Any and all input/advice/tips are appreciated.
Thanks.
