This model is what we call the ‘chromatic half’ and needs to be paired with the PP7021 to create a fully chromatic instrument. Build quality is excellent with aluminium note bars and a solid ply birch resonator box. This instrument has the notes C#29, D#31, G#36, C#41, D#43 and G#48. The F# and Bb note bars come with the PP7021. These metallophones are tried and tested by musicians to ensure this high standard.
