It was in an old guitar case. It's very heavy and is estimated to be about 40 years old. It's now discontinued and can't be found in musical instrument stores or online, so it might have some rarity value. I haven't opened the box, but it's in good condition. The rubber parts might have deteriorated slightly with age, so they might need to be replaced. Is there anyone who used to use this, or who has fond memories of it? What do you think? I will ship it via Yu-Packet Post Mini.
