The suggestion from one of our readers (thanks, Erez!) is to use Task Unification on a guitar. His comment suggests that players have trouble keeping their guitars in tune when playing in a band. They need to reduce the time it takes to re-tune between songs. I liked this assignment because I play guitar, and I have a small collection of electric guitars, an acoustic guitar, and a banjo. This will be the first time I have applied a systematic innovation process to invent new guitar concepts. Let's see what happens.
