Corrections: The Suzuki S-32 range is F4-C7. The last Yamaha listed should be “P-S25F.” If I slipped up on something else, I’ll appreciate being corrected.
Three models I forgot to mention:
(1) The Mylodica Soloist, F4-C7. The melodica inside the wooden box, though, is a Suzuki S-32 Melodion.
(2) The new Hammond SS, S-27 Melodion, F4-G6. I don’t have one of these so am unable to make comparisons with other Suzuki models.
(3) The plastic tray Suzuki MX-27S, 1998-present, also F4-G6. I also don’t have one of these.
