RACKTUNER BTR2000

Bass (BAS)

This mode is especially well suited for a 6-string bass. (B - E - A - D - G - C)

Baritone (brt)

This setup helps you tune a guitar to a baritone tuning, in which each string is tuned 5 half-tones (a fourth) lower than a normal guitar. (B - E - A - D - F sharp - B)

Banjo (bjo)

The very widely used banjo tuning is made possible with this mode. (G - D - G - B - D)

Ukulele (ule)

The BTR2000 recognizes the notes of the open strings of a ukulele. (G - C - E - A)

Open D (o-d)

The open strings are tuned so that they create a D major chord. (D - A - D - F sharp - A - D)

Open E (o-E)

The open strings are tuned so that they create an E major chord. (E - G sharp - E - G sharp - B - E)

Open G (o-G)

All open strings create a G major chord. One good variant of this is the following tuning: G - B - D - G - B - D. Since the low strings are under very high tension in this tuning, the strings can also be tuned as follows: D - B - D - G - B - D

Open A (o-A)

The tuner recognizes only the notes of an A major chord. (E - A - C sharp - A - C sharp - E)

DADGAD (dad)

In this mode, the tuner recognizes the following notes: D - A - D - G - A - D.

+When it is switched off, the BTR2000 stores the selected tuner mode.

The names of the notes are shown on the display as follows:

4.3 Calibrating the tuner

To give you every available option for tuning your instrument, you can change the setting of the standard “A” pitch. In order to clarify what this involves we will take a slight digression.

The so-called standard “A” pitch has risen over time since its initial measurement: The tuning forks used by Bach, Händel or Mozart were at 415, 420 or 421 Hz (cycles per second). Today’s orchestras tune to an “A” of 444 Hz. The Berlin Philharmonic is right at the forefront: their standard “A” is 447 Hz.

The pitch of the standard “A” on the BTR2000 is set at the factory to 440 Hz. In the event you want to play with a major orchestra that tunes to a standard “A” of 444 Hz, you need a function that will let you change the frequency of the “A.”

+The calibration settings are stored even if you switch the BTR2000 off.
