The Suzuki SUB30 Ultra-Bend is a truly revolutionary diatonic harmonica! Suzuki's advanced reed-plate technology has enabled us to fit 30 reeds in the size of a normal 10-hole harp, 20 on the top reed-plate and 10 on the lower. The extra 10 are sympathetic reeds that allow you to bend the bottom 6 blow notes and the upper 4 draw notes, using the same type of easy controllable technique as the normal bends. The harmonica becomes chromatic through simple bending technique. The chart above shows all the notes you can now get with draw and blow bending throughout the harp. SUB30 Available in 3 keys : C, A and D
