Swoop LED Display: Gives you the best visual cue for easy
tuning, especially from a distance. It works like a bar graph of
your pitch, sweeping up for sharp & down for flat.

Dual Tuning Modes: Never again will tuning be a dreary pre-
lude to greater things with Sabine’s Dual Mode LED tuning dis-
play. Standard Mode gives you a bar graph reading of your
pitch. Strobe Mode shows moving sweep of pitch. Both are
more accurate than conventional needle-style displays.

♦ If you have difficulty getting a note to register on
the tuner, touch the other strings lightly to stop their
sympathetic vibrations.
♦ Use good strings. Old strings lose their uniformity
and do not vibrate evenly. Remember to stretch your
new strings out; new strings stretch flat as you play.
♦ All sources of friction cause tuning problems. For
example, if the slot in an instrument’s nut is too
tight, the string will be pulled flat as it is played. A
tight nut (or capo) will cause the string’s pitch to
change in steps rather than evenly.
♦ Avoid pressure on the instrument while tuning. Even
moderate pressure on the neck of a guitar will cause
a noticeable change in pitch. Also, press the strings
straight down to the fingerboard. Bending the
strings sideways is very common, especially on dif-
ficult chords, but causes the strings to be pulled
sharp.
♦ Pluck one string at a time.
♦ Pluck the instrument once per second to keep the
note “fresh” while you are tuning. Notes go notice-
ably flat a second or two after being plucked. If tun-
ing a higher-pitched instrument (such as a mando-
lin), pluck a little faster; for a lower-pitched instru-
ment (such as a bass), pluck slower.
♦ Do not pluck loudly. Generally light to medium
volumes provide purer tones that are easier for
tuners to analyze.
♦ Fingernails and flat picks add overtones and slow
the tuning process.
♦ Tune from a pitch that is flat up to the pitch you de-
sire. This procedure removes any slack in the gears
of the instrument’s tuning heads. If you tune from
sharp to in tune, the gears will slip as you play,
and the instrument will go flat after a few minutes
of playing.
