I'm going to start tinkering with a few simple schematics and I figure the best way to do it is to practice on some breadboard. I've got a bunch of stuff bookmarked and am slowly working my way through it but sometimes I see people mention that you don't need to solder on breadboard but then sometimes I see examples where it has been soldered. If you don't solder it how do you keep the connections intact between the different components? If you run lead wire how do you connect it to each component without solder? Also, is it safe to run a schematic from breadboard so I can hear what it sounds like? I'm talking about simple fuzz or boost pedals, no high voltage tube pedals or anything.
