Uses the same construction as the classic Marine Band 365, but the sound range is extended downwards instead of upwards.
additional lower octave with identical tuning and bending capabilities as for channels 1-3, but one octave lower.
This allows for typical phrasings by using draw bends to be played over a range of 2 octaves. Confused ? just buy one and play...all will become clear.
For the G and A major harmonicas, think of a high tuned harmonica with an extra octave in the lower range.
