Collection: Three Voice Melodeons

A three-voice melodeon is a diatonic button accordion equipped with three sets of reeds for each note on the treble end, allowing three reeds to sound simultaneously for a deeper, richer, and more powerful tone. 

Reed Configuration: Most commonly tuned as LMM (Low, Middle, Middle+), where the "Low" or "bassoon" reed is tuned an octave lower than the standard middle reeds.
