MBCH - Chromatic portion for MBD
The MBCH Chromatic portion is use with the MBD Bass Diatonic Metallophone.
Extra wide bars precisely tuned to A = 440 Hz and overtone-tuned. Resonator box onterior especially tuned and design for optimal and equal resonance.
F# and Bb bars are laways included with diatonic instruments and should therefore be added to chroamtic sections purchased to complete the full chromatic instrument.
