商品概要:1988年製YAMAHA SESSIONⅡ-712Jに装着されていたローラーナットです。

YAMAHA SESSIONⅡシリーズの900J、700Jシリーズに装着されていたパーツです。

同型のものでAria proⅡではLFN-41(ロック・フリー・ナット・41mm)という名称で呼ばれましたが、YAMAHAでは特に、名称はなくローラーナットという名称です。

以下は全く同型であるAria proⅡ LFN-41の説明です。

当時(80年代末)あたりから弦をロックナットでロックすることによりチューニングは安定するものの、どうしても音が単一化しやすいということがちょっとありました。

自分のように見た目さえよければ音なんかどうでもよいという人は置いておいて、結構気にされている方は多かったようです。

で、各社チューニングの安定と弦をナットでロックしない方法を模索しており、当時のAria proⅡはロック・フリー・システムというものを編み出しました。

ローラーサドルブリッジ(LFT-1、LFT-10)、ローラーナット(LFN-41)、ロック式マシーンヘッド(LFM-60)という組み合わでMAGNAやAQUANOTE,VIPERとかに搭載しました。

全部一式GOTOH製のパーツです。

先ほど、カタログを眺めていて気付いたのですが、それぞれロック・フリーが型番頭にきて、トレモロ、ナット、マシーンヘッドのイニシャルになっていたのですね。

ちなみにこれはAria proⅡの呼称で、YAMAHA SESSIONⅡシリーズにも同ナットは搭載されています。

特徴としては0Fを兼ねるロックナット同様の位置に上止めで装着されます。

ですのでナット幅さえ合えば、ロックナットの代わりに装着できそうです。

サイズはナット幅が実寸で41.1mm、横が11.9mm、最大高が6.5mm。

磁石に付くので素材は鉄製のようです。

仕上げはゴールドです。

程度はゴールドメッキ特有の色あせはないですがくすみがあります。

とはいえ十分ゴールド感はあります。

送料はゆうパケットminiで180円。

ロックナット代わりにもできそうなので、結構使い道の広そうなローラーナットです。

実際Aria proⅡではロック式ブリッジとも組み合わされて装着されている機種もあります。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters).

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
