Anything apart from the two mainstream default harmonicas (Solo-tuned fully-valved chromatic, and un-valved Richter 10-hole diatonic). Alternate tunings, different construction, new functionality, interesting old designs, wishful-thinking... whatever!
BASIC CONCEPT: A small harp to carry around and reach for when you want to back up some blues/rock/pop but not do big, soaring solos.
WHEN/HOW: 2015?
LAYOUT:
DETAILS: This is a more sophisticated version of my "Chord Buddy" for Big Six, because its tones are more carefully arranged for some draw-bends and some 4-tone chords.
