I've been doing a lot of research on electronics in general and got a book on tube amp maintenance and construction, and I'd like to build a stompbox. The only thing is, my only exposure to electronics is really guitar wiring and a few computer things (replacing components on a mobo, rewiring pinouts, etc.). So my question is: in order to avoid wasting parts, would it be in my best interest to invest in a decent breadboard instead of buying PCBs, just to test out these projects, and then when I'm ready go all out with PCB and chassis, or should I just get what I need when I need it and hope for the best? Do I even have the concept of what a breadboard is for right? Help!
