I see that there are actually two other Suzuki sopranos, the S-32C (or S-32, which I guess is an earlier model) and the MX-27S. The MX melodions are Suzuki’s middle line, while the S-32C appears to be a member of the higher line that includes the M-32C, M-37C, and A-34C, all of which sit in a metal tray. The S-32C (or S-32) appears to me to be what’s inside the soprano Mylodica. But I’ve just ordered an S-32C and will be able to verify that and to make comparisons with the M-32C, etc. Kevin has a review posted for the S-32C.
