The first time I tested the Suzuki Pro-37v2 (with the white tube) 3 years ago, I noticed the famous resonance detail with the bass notes, but this year I bought another one (with the black tube) I think that recently built and did not have that detail in the sound.
In the same way this “new” Suzuki Pro-37v2 has an increase of middle-high frequencies which gives too much presence to the sound (my neighbors know it) But ! when recording, it allows me to equalize by reducing frequencies and find the sound I am looking for. This would not result with other melodicas, for example the M-37C, because it would have to increase frequencies and perhaps it would not appear what I’m looking for.
In summary, with melodicas the subtractive EQ is more efficient.
The sound of the Hammond pleases me more but 44 keys seems a lot to me for a melodica.
Hopefully the Hammond PRO-37MIX will appear, a mix of the 44 standard and the 44 Hyper.
