Cherub continues to deliver value to music consumers.  This tuner is by far the best priced tuner with key transposition feature on the market.

As with all Cherub tuners, this model offers supremely accurate tuning and fast response time.  This tuner combines the best of the 3 technological worlds of digital VU meter, LCD and LED.  Digital VU meter offers the most accurate response to tuning, perfect for precise tuning.  LED tuning guides offers the easiest visual tuning indication.  And LCD offers the best readout of tuner operation.

This chromatic tuner can tune all 12 notes.  The tuner also has 4 key transposition modes (C, Eb, F, Bb).  Transposition is used when tuning instruments played in different keys.  For example, piano, violin, guitar, etc. are played in the key of C while alto saxophone is played in the key of Eb and French Horn is in the key of F.  

The # and b mode of the tuner allows the half notes to be displayed all in # or in b.  This is used as a preference by instrumentalists.  The tuner features a very easy to read digital display and easy to use button operation.  The display registers the note name and mode automatically.

The device has a built-in mic but also comes a standard 1/4" (6 mm) input jack that allows the tuner to be used with a pickup for improved tuning.  With the built-in mic, this tuner can be used in a hands-free fashion while with a pickup, background noise will not get transmitted to the tuner.

This tuner is compact pocket size.  It can easily fit into any case or bag.  It also comes with a built-in stand that allows the tuner to be placed in a easily readable position.  This tuner even has a strap hole built into it, like the ones on cameras.  You can attach a strap to the tuner and carry it or hang it.  As with all Cherub metronomes, this model is very well built to resist damage from accidental drops.
