The Hohner Echo Celeste is a tremolo harmonica, which means it has two reeds per note and can produce a great vibrato. This harmonica is better suited to classical or gospel music than to blues. The Echo Celeste has 24 holes and 48 reeds. The tone is beautiful, but it can be difficult to get enough volume to really project in a large venue. That's because the Echo Celeste requires a lot of breath to produce each note. Reed issues are fairly common with this model, but it's still worth it because of its versatility and relatively low cost. It is also available in multiple keys.
