Now that that's settled, here's an affordable tuner that sports several cool features that go beyond the capabilities of most tuners. The Behringer Chromatic Tuner TU300 not only handles all the standard guitar and bass tunings, it also accommodates you if you downtune your instrument or employ exotic tunings of your own design. The TU300 gives you three guitar modes (regular, flat, double flat), three bass modes (regular, flat, double flat), plus a chromatic setting. If you're a gigging guitarist or bass player, the Behringer Chromatic Tuner TU300 is essential equipment.
