About

In 2007, Roger Schlichtig set out to create the greatest tuner that he could. He wanted to make something that was special, something that would blow every other tuner out of the water. With a bit of elbow grease, the Turbo Tuner was born as the fastest and most precise tuner that you could get your hands on. Through its various forms over the years, the Turbo Tuner has maintained its status as one of the most capable tuners ever made. We're proud of that.

How it Works

It might feel like voodoo magic, but the Turbo Tuner is still just a tuner, albeit a special one.

Strobe Tuners work by comparing the frequency of a note with a reference frequency. This reference frequency is generated by a rotating disk with an alternating pattern printed on it. As the disk spins, it is illuminated by a strobe light that displays any variation in frequency. Microscopic inaccuracies become easily observable with this method, giving strobes a distinct advantage over other types of tuners.

Luckily for you, the Turbo Tuner is a fraction of the size of a traditional strobe, meaning you can throw it on your pedal board without a second thought. It’s also made with solid state components, meaning there aren’t any mechanical parts to where out. So long as you don’t dunk it in a vat of acid or throw it into a mosh pit, your Turbo Tuner should outlive you.
