Hohner Corona II in A/D/G. A three row instrument, with 31 treble keys and 12 basses. Tuned to give a light tremolo and to blend with the basses. The standard Hohner tuning is often brash and sounds sharp in relation to the basses. This instrument now has a sweeter sound than the standard tuning style.
The outside row of buttons in key of A give some useful note reversals not found on a DG melodeon. Specifically push E and pull D. If you happen to play across the G and D rows then familiar key patterns are also available across the D/A rows, without requiring hours of practice to learn new patterns.
