From the manufacturer TU-1000 Stage Tuner PRO-CALIBER TUNING FOR THE STAGE FLOOR The new BOSS TU-1000 is a tuner fit for a rockstar. The new flagship of the famous BOSS TU-series is built tough and made for the stage floor. Its large, high-intensity LED meter provides perfect visibility on dark stages or outdoors, while the ultra-smooth and accurate motion of the tuning meter makes tuning fast, easy and accurate. Ultra-smooth, accurate motion and superior visibility with the meter’s oversized LED Accu-Pitch uses the motion of the meter’s lights to show when tuning is complete Two display modes: Cent (LED functions like a needle-type meter) and Stream (fluid light motion indicates when notes are out of tune) Powering up the tuner automatically mutes the output signal, allowing you to tune without outputting Handles open tunings, DADGAD, and other alternate tunings, as well as dropped tunings up to six semitones below standard Two outputs, including one with direct signal flow Drop-Tuning Support/Tuning Modes For guitarists who drop-tune, the TU-1000 offers a special Flat Tuning mode, which lowers the pitch one or more semitones below the note shown in the display. The display changes according to your choice, from ”lowered one semitone” down to “lowered six semitones”.The TU-1000 offers a variety of tuning modes. In Cent mode, the LED meter functions as a needle-type meter, with BOSS pinpoint accuracy. In Stream mode, the stream-like motion indicates when notes are out of tune. The Pitch indicator illuminates when the target pitch is met. Connectivity There’s plenty of I/O on the TU-1000’s rear panel. The INPUT jack also doubles as a power switch. Connecting your guitar turns on the tuner’s power; disconnecting from the plug turns the power off. The OUTPUT jack is for connecting to an effects processor, guitar amp, or other such device. Typically the output is muted while the tuner is on, however, you can specify whether the signal is output regardless of whether the tuner is on or off. The PARALLEL OUT jack lets you split the signal from the input jack and send it to a connected effects processor or guitar amp. The TUNER ON/OFF lets you connect an external footswitch (FS-5U; sold separately) for powering the tuner on and off remotely. Floor Control The high-visibility design makes the TU-1000 a perfect choice for the performing guitarist. Positioned on the stage floor near your pedals or in your pedalboard, the TU-1000 can be easily seen and operated in the darkest stage environment. And from the audience’s view, the glowing blue BOSS logo on the TU-1000’s rear panel is an eye-catcher as well.
