PROFESSIONAL RACK-MOUNTED TUNER

All guitarists, as well as bassists and keyboard players with older synths, know how important it is to keep their instrument in tune with professional precision, especially during live performances. Even with the most modern tuners, it can often be difficult to quickly check your instrument between songs. TerraTec's new SINE CT1 chromatic tuner, a single-unit rack-mount tuner, helps.

Whether you're sitting in a noisy room or in the middle of a recording session where complete silence is essential, the SINE CT1 will keep you in tune in any situation. Simply plug your instrument into one of the 6.3mm jacks (identical jacks are available on both the front and rear panels) and touch a string or fret. The 7-segment display automatically shows the exact pitch of the note played while indicating any possible tuning adjustments. The "Mute" button or optional pedal allows you to mute the instrument's output while tuning.
If you want to rely solely on your ear, you can use the built-in tone generator, which covers the frequency range of 438–445 Hz in 1-Hz steps. If maximum precision is what you need, the SINE CT1 will surely become one of your most prized pieces of equipment.

Features

Tone generator adjustable from 438 Hz to 445 Hz in 1-Hz steps

Mute function can also be activated via the optional control pedal
