43 tone just intonation electric guitar (Monophony). Built with all pitches in Partch’s 43 tone just intonation available. Its quite impractical and plays a bit as a lumpy fretless guitar but with care and practice its possible to play, though chords are very difficult.

Chromolodeon/ Accordion based version of Partch’s instrument. Two accordion keyboards were run through a bandsaw then bolted together. The reed banks were removed and reworked to allow the 8 octaves to play 43 tone just intonation and to give the instrument an audible range of two octaves. It uses only one reed bank and the bellows are used as foot pumps to run the instrument.
