Sound Modification Unit A Improved Version ver2 Disassembly Special Tool SET All stainless steel (rust-resistant) can be disassembled by hand. Other special tools are made of iron and will rust. By installing this part, a sound will be produced when the handle is rotated in reverse, and appropriate tension will be applied (adjustable), preventing backlash. Installation can be done with the original screws in about 10 minutes. We provide support for easy installation! We also adjust the initial tension. Just install it after purchase, and you're good to go. Previously, someone falsely requested photos of my parts and didn't respond. They then copied and produced them in a factory for sales purposes, complained about others, and used photos without permission. What do you all think? It's infuriating. They only copied the form and lack the technology. Please be careful of sellers with bad reviews. Good parts produce good sound quality from the start, even with weak tension. As the author of the Yaen, I have improved and produced these parts, and I have repeated field tests, so they are safe for long-term use. Loud sounds give squid a sense of discomfort due to the sound from the main line, and strong tension also wears out the core of the parts quickly, resulting in many disadvantages. If you remove the spring from the pin in photo 5, it becomes difficult to attach and tends to come off easily, so two substitute tubes are included as a bonus. If you use them instead of the spring, you can easily remove and reattach them many times.
