Anyone who knows about chromatic harmonica, I would like to ask if the hohner discovery48 and scx48 are the same performance instruments? Because

Yes!

The model: discovery 48 harmonica (D-48 for short) is a 12-hole chromatic harmonica from the German brand HOHNER.

Model: SCX-48 is a Suzuki 12-hole chromatic harmonica.

Yes, that's right! Both are really the same chromatic harmonica in terms of the nature of performance of playing. They are even the most similar harmonica in terms of geometric shape. The only difference is that the Discovery 48 has square holes and the Suzuki SCX-48 has round holes. The performance is the same, but the taste is different. Early chromatic harmonica are square holes, in recent years the new models are more round hole shape, it is generally believed that in containing the instrument, round holes than square holes will be better airtight, I also have the same feeling. In terms of price, the SCX-48 harmonica is generally higher than the Discovery 48 harmonica.
