The BOSS stompbox tuner's accuracy and convenience has become an industry-standard since its inception in 1998. It boasts the widest tuning range in its class, and with seven tuning modes and savable display style choices, its ease of use is hard to beat. The predecessor of the current TU-3 model, its notable difference is a 7-segment LED display compared to the 21-segment display of its newer counterpart. One of two used TU-2 tuners listed, this one has slightly more cosmetic wear.
