All the parts needed to set up the circuits in my introductory How-To article and the one that follows on the Bare-Ass Boost. You also get the organizer. The article will walk you through the basics of interpreting a schematic, JFET operating principles and parameters, setting up the circuit and tweaking performance. The result can be turned inexpensively into a professionally useful pedal. Does not include a breadboard or a multimeter, which you can find in Prototyping Tools here or at other sources.
