1970年製 カスガのダブルオーサイズ  モデルNO.MF-160

年式の割に美品で、貝のヘッドロゴやこげ茶のべっこう柄ピックガード、ハカランダ?のヘッド突板が渋い一品です。

音と演奏性の向上を目的にかなり手を入れてありますので、ノーマル品ではありません。
以下ご確認ください。

【改造および修理内容】上から順
1.糸巻交換
 (中国製ですが操作感は良好。カバーにネジ締め用の穴をあけてあります。)
 (また、1、3弦の軸に弦切れ防止の0.3ミリ真鍮のカバーを巻いてあります。)
2.ナットリシェイプ及び溝調整
3.ロッドカバー自作
4.独自に考案したネックヒール切り継ぎ工法でネックの仕込み角を修正
 (調弦時の12F弦高:6弦2.3mm、1弦1.7mm)
5.ブレイシングを大幅改造
 (大きな点は、開脚が大きくてブリッジ端に十分ラップ出来ていないXブレイスに添え木。
   その他、削りと追加により、振動が広範囲に及ぶよう全体にバランス取り。)
6.ブリッジ再接着
 (一旦ブリッジを完全に剥がし、トップの塗装をブリッジ形状に剥がした上でタイトボンドで再接着。)
7.サイドのウエスト部1カ所割れ修理
8.サドルは純正の牛骨で、フィッティングのみ調整。
9.エンドピン交換

【諸元その他】
トップ:スプルース
サイドバック:マホガニー
弦長:627mm
ナット幅:43mm
ロッド:正常。5割締め
フレット減り:ほぼ無し。使用感なく、ローポジションの部分的な減りもありません。
ブリッジ下のトップ膨れ、およびブリッジの傾きがあります。(画像でご確認ください)
弦:アーニーボウルのライトゲージ。(交換から1か月経過)
音:トップ全体が響き、豊かな鳴りと心地よい倍音。入念に調整してあります。

ケースは付きませんが、プチプチとダンボールでしっかり梱包し、ゆうパック元払い160サイズで発送します。

なお、新規の方の入札は削除しますので、ご容赦願います。

ブリッジの傾きについての補足
弦の70kgもの張力を受けながら、できるだけ傾かないよう耐えるブリッジの構造的工夫とは?
それは、ブリッジがトップ板とブリッジプレートだけでなく、ブレイスにも乗っているから。
Xブレイスの場合、開脚した左右の足がブリッジ両端を横切り、ブリッジを支えています。
一度、お手持ちのギターのホールにLEDスタンド等の明かりを入れて中から照らしてみてください。
Xブレイスの足がブリッジ端と重なっていることが良く分かります。
そしてこの重なりは、強度的なことだけでなく、音を左右する要素であり、
その重なり量は、製作家が神経を使って決める重要な部分となっています。
さてこのカスガ。ほとんどラップしておらず、ブリッジ端の角をわずかにかすめる程度。
それがこのブリッジの傾きの一つの要因となっています。
それを改善するため、両方の足の内側に添え木してラップ量を増やしました。
(全体として太くなりすぎた分は、高さを削って調整しました。)
また、要因のもう一つは、遠い方のトーンバーが遠すぎてお腹の膨れを効果的に押さえれていないことです。
その対策としては、程よい位置にトーンバーを追加しました。(遠い方のトーンバーは半分以下の高さに削りました。)
それら二つの対策により、当初ひどかったブリッジの傾きが、完全に解消は出来なかったものの、
許容できるレベルまで改善できたと思っています。
また、構造手に対策したことで、今後の悪化も心配ないものと思っています。

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). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

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.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.
