Hi all, I'm new to electronics and have been using a few different books to start learning. The first project I plan on trying is a fuzz-box as a guitar effect. The schematic provided is shown below. There are a few icons used that I can't find in any references. I've used ms paint to circle the icons I don't understand. Also, I'm quite sure this effect needs a power supply, but I don't see where that is on the schematic.
Thanks for any assistance!
