The first Roadie tuner was a modern marvel. An automatic guitar tuning system, the little device connected to your phone to listen to your guitar strings and then set them to the proper tuning using an internal motor. The new model, the $ 129 Roadie 2, is even cooler.

I’ve been using the Roadie 2 for a few months now and I’m hooked. I was never a good player or tuner – my ear wasn’t quite right and even with tools I couldn’t get my guitars exactly in tune. Now, however, with the Roadie 2 I just place the winding end on the pegs and press a button. A quick pluck of the string and you’re tuned in seconds.

The Roadie 2 is completely self-contained and charges via USB-C. It has a built-in vibration sensor that can also asses the current string and change the tuning accordingly. The system also allows you to add multiple stringed instruments – you can set up profiles for your electrics and acoustics and even your banjo . You can also tune them to standard or even open tunings. The high-torque motor spins the pegs quickly and effortlessly and you can wind and unwind your instruments as well.

The team kickstarted the Roadie 2 last March and began shipping this year. I’ve been using it to tune my guitars since I got it and it’s worked quite well except for one unfortunate incident while winding – and overwinding – a kid’s guitar. An app included with the package lets you control the instruments and the tunings.

I know some guitarists can tune to the sound of overhead fluorescent lights and still others are OK with a quick listen to a digital tuner. I’m neither of those. The Roadie 2, then, is a godsend for those of us cursed to the never-ending torment of being really bad at guitar. At least now I can be really good at tuning.
