This 3rd bridge instrument has six sets of chorused strings. All 12 strings have 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 (or any "non-scale", for noise musicians). The harmonic sound is very full and consistent, not to mention controllable! Lots of sonic potential. Available for $1200 AUS.
