Thanks again to Henry Kaiser for the tip on this fascinating Australian instrument maker. New Complexity makes two guitar-like instruments: the Harmonic Isolator and the Harmonic Master. Here is a peek at a potential source of some interesting music.
The Harmonic Isolator is a unique 3rd bridge guitar. The silver frets are all harmonic notes, which excite harmonic frequencies behind the bridge when played. The seven gold frets are notes from the western 12-tone scale, designed to allow players to approximate material they might play on an ordinary guitar. The harmonic ratio between the two string fields is 4:3 and it is typically tuned A to A. The Harmonic Isolator can also be fitted with a sustainer system, which enhances the ambient and ethereal sound of the instrument.
The controls include three-way lever switches on the left and right sides, Volume controls and output jacks for each side, a mix output jack, which functions when nothing is plugged into left and right jacks, an on/off toggle switch for the sustainer, and a sustainer drive control.
This 3rd bridge instrument has six sets of chorused strings. Each string has independent tuning positions behind the bridge. The anchor points behind the bridge are fully adjustable with the maximum harmonic ratio being 1:3 and the smallest around 1:6. You can tune the notes behind the bridge to pretty much any scale you want.
