Shaper 1a Completely handmade at Lavoro. It produces sound evenly across the entire range. It's a bit heavy, and it plays strongly with a lot of breath, while also producing quiet sounds with less breath. Recommended for those who like reeds with resistance. This is the lightest of the four, and I think it's the easiest for anyone to play. ※ Preferences vary depending on playing style and instrument. I tend to use a strong breath, so I sometimes intentionally play softly when writing my impressions.
