Cons:
- Not very accurate voted in upper position
- Bass is compared to the middle too loud
- 444Hz, for my monthly jam session (440Hz) unfortunately unsuitable
(Hohner comment to pitch the series: 441-444Hz)
- No contrast between the upper and lower row of keys, with sessions in the dim light can be a problem for uncertain players by glossy however negligible
Conclusion:
A lot of fun, sounds nice, is for the intended purpose of me but unfortunately unsuitable,
If you only need an accompaniment to a permanent player with flexible mood which may well access.
Hohner turned in demand for white row of keys and 440Hz tuning cross however.
Curiously, the "Perfomer 37" is not supplied, which the black / white version of the Super Force 37 is apparently from the German company Hohner to Germany. Komische company policy.
