Or more accurately, strum all your strings and instantly find out which ones are out of tune. The PolyTune by TC Electronic bills itself as a revolutionary new way to tune your guitar. You strum your guitar once and the readout will display which strings are out of tune. You can then tune those strings individually with a more traditional display. You can check out a lengthy review of the PolyTune here. This actually does appear to be a timesaver but will set you back around $100. If you don’t perform onstage much or don’t want to spend the dough, they’ve also released a free Polytune iPhone App. There are two videos below. The first is a demonstration of the pedal by a dude with a sweet Danish? accent that will give you a good idea of how the PolyTune works. The second video shows the iPhone App in action.
