Practice mute that allows you to practice blowing with all your might at home. Yamaha Silent Brass (old type) Pickup Mute PM3 and Personal Studio ST5 for French Horn. The pickup mute has high sound-dampening capabilities (even when played forte, the sound is only a whisper), and the intonation and resistance are good, so I used it as a practice mute during the COVID period. It's larger than the latest models, so it sticks out of the bell and doesn't fit in the case, but it was great for practicing at home (at night) before rehearsals or performances. The Personal Studio has two input jacks from the pickup mute and two stereo headphone jacks so that two people can play together. You can duet. Furthermore, there are three reverb modes: lesson room, hall, and church, which is interesting to select. (You can feel like you're performing in a hall with good acoustics, accompanied by an external sound source.) I bought it about 20 years ago, used it for 2-3 years, and then put it away, and used it again during the COVID period. There is no outer box. Brand: YAMAHA Color: Black Personal Studio operating condition: Good There is age-related deterioration (cracks) in the urethane resin of the bell insertion part of the pickup mute, but there is no problem with use. The instruction manual was stored on the bookshelf, and it is in a somewhat used condition. Please use your own stereo headphones. Please understand that this is a used item. It's a great item to enjoy at home if you try it.
