A no-nonsense, high-precision chromatic tuner pedal for guitar and bass. It features a large, high-contrast LED screen and ultra-fast pitch detection software that makes tuning quick and easy for musicians of every skill level. When 2NR is activated, the output is muted. When the pedal is not in use, relay-based, true bypass switching ensures that 100% of your tone passes through the pedal without any loss of fidelity. Housed in a robust aluminum chassis, 2NR is built for a lifetime of onstage performance. Pigtronix 2NR runs on standard 9 V DC power.
