Standard or extended scale
The archive includes equal-scale instruments and designs with longer bass strings. Extended bass strings and fan frets are different constructions; one should not be used as a name for the other.
Nylon / Instrument family
Multi-string Classical
Seven, eight or ten strings. A range built around the music, not just a wider neck.
The playing brief
What makes this direction different?
Additional bass strings, altered tunings and extended repertoire each ask something different of the instrument. Begin with the pitches you need, then choose the number of strings and their speaking lengths.
Spacing and reach
Nut width, bridge spacing and the position of additional strings are designed together. The goal is a usable instrument in both hands, with access to the notes your repertoire requires.
Beyond the familiar counts
No. 533 is a documented nine-string commission with an extended ninth string. Other counts begin with an individual design discussion, rather than a universal specification.

Seven, eight or ten.
7-string Classical
One additional string. Several ways to extend the instrument.

Before you choose
A few useful answers.
Should I choose more strings or a longer scale?
That depends on the intended tuning and the register you want to add. A string count alone does not establish the pitch, tension or response. We review those choices together.
Are fan frets and ArcFret the same?
No. Fan frets describe different scale lengths across the strings. ArcFret describes curved fret geometry developed for intonation. Compatibility with a new multi-string design requires individual assessment.
