The Turbo Tuner is a musical instrument tuner with the precision and features of the best strobe tuners, in a compact size at an affordable price. A strobe tuner works by comparing the frequency of the note being tuned to a reference frequency. In a mechanical strobe tuner, this reference frequency is generated by a rotating disk with an alternating white and black pattern printed on it. As the disk spins, it is illuminated by a strobe light which is driven by the input signal. Differences in frequency are clearly shown as a rotating pattern in the disk. Even small differences in frequency are quite observable, giving a strobe tuner a distinct advantage over other types of tuners. Unlike a mechanical strobe tuner, the Turbo Tuner is 100% solid state. There are no moving parts to wear out, and this makes it smaller and less expensive, and gives it a faster response.
