We got Kits!
Just released our Sound Urchin Kit and have two versions available, one that is a beginner friendly kit and another that comes with a wooden cigar box and a metal battery holder. Just about everything you need to get your Sound Box up and rockin’.
Really simple build, very few parts, super powerful sound. I also put together a short build guide with photos for users who have never put together a kit.
Advanced builders can mod the kit by adding a volume control, adding gain controls (pins 1 and 8 are unused but can control gain), or utilizing the kit as a guitar effect (omit the piezo for another audio jack and you have a boost pedal). The kit works great as cigar box guitar pickup as well (volume control recommended).
