I'm  trying to figure out if these things are worth building, Occasionally you see prototyping pedals where all the dials and switches are built into a pedal, and you get to arrange all the electronic guts (ICs, resistors, caps etc.) to make any pedal you want, and fully customizable. So basically it's a shell of a pedal, where without soldering you get to make/modify any pedal you want, and you can even build/tweak exact replicas of almost any pedal. If it was easy and cheap enough to do:

Would you ever use one to sculpt your unique tone?
To learn electronics for fun?
Or if you're electronics savvy already, would they seem useful to streamline pedal projects?
