Tunic Guitar Classic

Tunic Guitar Classic$39.99 from Bernhard Stopper Tunic Guitar Classic

Tunic® series provides the most precise tuners available for the iPhone/iPod touch 2G for professional studio use. Operating at a frequency resolution of less than 0.05 cent, beating even decent hardware tuners. Tunic®´s advanced adaptive algorithm handles string inharmonicities automatically whithout the need for corrective offsets.

Exclusively featuring StopperStimmung™ (1988), a slightly stretched tuning creating an amazing and clear sound on your instrument by the tunings recently discovered (2004) stunning structural symmetry. The necessary temperament compromise is strongly lessened by symmetrically interfering harmonics making chords to appear as beeing pure tuned.

“…The synchronous, beatless effect of this tuning seems real…” K. Swafford, Piano Technicians Journal, March 2009, USA.

The essential of a tuner is tuning quality, not features. Choose your appropriate tuner out of three available guitar versions, to suit your specific needs:

The basic version provides normal pitch (440 Hz) and classic EADGBE tuning template.

Classic EADGBE tuning template and variable pitch selection between 415 and 460 Hz and double sensitivity for the professional classic guitar player.

TUNIC GUITAR PRO: The full version for the professional user requiring more tuning settings. Provides variable pitch (415-460 Hz), a selection of common open tuning templates (Classic, Classic ♭, Open E, Open G, Open D, Open C, DADGAD, Dropped D, Dobro) and highest sensitivity (0.02 cent resolution). Capo use on fret 1-5 supported, what also allows verification of saddle compensation for optimal nut height / nut distance on fret 1.

iPod touch 2G requires iPhone headset with built in microphone. Original iPod touch is not supported.

As the extreme precision requires a high amount of processor performance, note selection is manually.


To change pitch, push on the pitch number and edit pitch as desired.

Green pointer:
Fine tuning resolution: 0.025 cent in a visible range of +-5 cent

Yellow pointer:
Coarse tuning resolution: 0.25 cent in a visible range of +-50 cent

Pluck the string to be tuned about one time per second, while muting the other strings. To handle the fine tuning indicator on this extreme precision level, measure the pitch by very small or no string tension changes. This requires some experience even for professionals but is honoured by an uncomparable sound experience.

Always tune your instrument in 2-3 cycles, as every change of one string affects the other strings. Tune your instrument often to achieve a good tuning stability. Pluck the string with a plectrum to produce an overtone rich sound with the microphone close to the instrument.

When comparing with other tuners, the order of the tuner used is very important: A less precise tuner usually measures to be “spot on” a tuning done first with Tunic and hence appears to deliver the “same” results as Tunic, due to its wider tolerances. Tune first with the less precise tuner to notice the audible differences Tunic can visually indicate.
