Sonor Meisterklasse GBKM 20 Deep Bass Metallophone Chromatic Add-On

If you already own the GBKM 10 deep bass diatonic metallophone and you're ready to take it to the next level, then this is chromatic add-on you need!

With this chromatic add-on, you'll receive 1 resonator box along with 6 bars - C#, D#, G#, C#1, D#1, and G#1. Because your original diatonic instrument came with mallets and the F# and Bb bars, they are not included with any chromatic add-on units.
