Thank you for viewing! I am selling this item due to moving and decluttering. This is the initial model of "Re:VIBRATION" for horn by the now highly-regarded NachtmusiK BRASS FACTORY. *I am currently a user of the current "Re:VIBRATION" model. This is recommended for those who find the current "Re:VIBRATION" model too resistant! I think it's also a great item to have as part of a collection. I used it extensively at first, so there is some wear and tear, but there are no performance issues. I would appreciate your consideration. Thank you very much! @FrenchHorn @CustomParts
