Tech Info & Updates
Welcome to Octave4Plus
Octave4Plus plain steel strings are different from standard
plain steel strings. With the average .007 or .008 plain steel
string, you are given the gauge information, but not the
specific pitch or scale length information.
We know that an .007 or .008 string at the 25.5" scale can tune
to E4 329.63 Hz, to the F4 above that, and the F#4 and G4 above
that. At this point, it has been "hit and miss" with G#4 and we
have yet to find a plain steel string (other than an Octave4Plus
string) that can actually tune to A440 Hz at the 25.5" scale. We
have heard rumors, but have yet to see or hear recorded video or
audio to authenticate these claims.
If you have tried to tune up to A4, then you know the all too
familiar "snap" before you reach A440 Hz.
Some believe that a thinner gauge string will automatically tune
to a higher pitch. This is not the case.
Octave4Plus strings are pitch specific for each scale length.
Octave4Plus strings are made to order.
Octave4Plus offers an .009 A440 string as well as an
.008,.007,.006 and .005.
All of these are designed to tune to
A440 Hz. There are several versions of each gauge of string,
each designed for your particular scale length.
Buying a 30" A4 string so you can tune to B4 at 26" doesn't
apply with Octave4Plus strings. You would want to order a B4
string for the 26" scale to assure that you have the right
string for the scale length and pitch.
Octave4Plus also offers companion E4 and B3 strings for Tonal
Unity with the high A4, Bb4 or B4 string.
Octave4Plus strings are made with the patented O4P ball ends.
These short video clips are provided to show those who have
trouble envisioning an open A440 Hz string at the 26+" scale
lengths, that these open string tunings are possible with
We will be adding performance videos featuring Octave4Plus
strings being played soon.
