SUZUKI SNB-48CVS Silencer System, with instruction manual. I am a chromatic harmonica instructor. This item was purchased by a student, but they never had the opportunity to use it, so they brought it to me. - It was only installed and used once, so the main body is in clean condition. - The case shows signs of aging, but the original material seems to be prone to degradation. My own and other students' cases have deteriorated similarly or even more. This product was reportedly stored at home for a long time without being used. - The main body has been completely disassembled and cleaned. - It can be attached to 12-hole chromatic harmonicas made by Suzuki (all models except Fabulous). If you don't have a compatible harmonica, the SCX-48 is recommended. - In my experience, when this product is fully installed, the volume is reduced to about 1/4 to 1/5 of the usual volume (the volume itself is reduced, but the resonance is suppressed even more). The sensation may vary depending on the original volume, but I think this product is recommended for those who find it difficult to practice in a residential environment. - Only the main body and the instruction manual are available for sale. Everything shown in the images is included. - If you have any requests for shipping date and time, please send a message immediately after purchase. However, please refrain from requesting a date more than a week in advance. 【Product Information】 - Model Name: SNB-48CVS - Brand: SUZUKI - Instruction Manual: User Set SNB-48CVS Instruction Manual - Case: SHINOBIX Case Thank you for viewing.
