Everything needed to set up the circuits in my introductory How-To article and the one that follows on the Ursa Minor. Includes the organizer, the small breadboard pictured, and several old-stock semiconductors that contribute distinctive tone. A super value, because the parts and materials can be re-used hundreds of times to try out ideas. The articles will walk you through the basics of interpreting a schematic, setting up the circuit, tweaking performance and mods. The result can be turned inexpensively into a professionally useful pedal.
