This is a Danish pickup, not sold in Japan. A person who returned from NY was using it, and it has a very natural sound. I collaborated on a group purchase, commissioned by the contrabass craftsman "FUJIYA." After negotiations, I was able to purchase directly from the Danish manufacturer at wholesale prices, making it possible to sell at the same price as in Denmark, NY, or London. 42,000 yen + consumption tax. Installation is easy, as it's clamped to the bridge, but you may need to shave it or insert a thin piece of wood if the size doesn't fit. Thin wood is available as an optional extra. The pickup is about 5mm thick, slightly thicker than an Underwood. If you can't do it yourself, FUJIYA (listed below) in the Kansai region can install it for 3,300 yen. https://strings-fujiya.com/ For other locations, a music store might be able to help. (Not guaranteed) A violin shop should be able to install it anywhere. The jack's cable tie is reusable. Here's the manufacturer's explanation: Planet Wing pickups offer high output and cover the entire frequency range. The lowest frequencies have excellent clarity, and the treble and midrange are warm, without the harshness often found in other contrabass pickups. They send a stable, powerful output signal to any amplifier, achieving a warm and balanced sound. - Brand: Planet Wing - Model: Pickup - Features: Provides a full spectrum of sound - Application: For double bass - Connection Type: Plug-in Get this unreleased-in-Japan double bass pickup!
