## Description

Nobody knows flat wound bass strings better than Thomastik-Infeld. SPIROCORE strings by Thomastik-Infeld have been legendary among upright bassists for decades. Now the electric bassist can also experience the Thomastik-Infeld sound. Thomastik-Infeld utilizes a highly pliable steel core which is wrapped with a silk inlay. The outer winding is a true ribbon flat wound constructed of a special nickel alloy. The result is an incredible depth of tone and an enhanced fundamental which is unavailable from any other flat wound.

Review: 一度試しにどうでしょう？＊追記あり＊ - あのピノパラディーノが使っているとのことで試しに購入し、もちろんプレべに張ってます。 個人的には知っているベース弦でダントツでテンションが緩いです笑 まあ好みは別れますが触ってれば慣れます。スラップしやすいです。 フラット特有の硬さが苦手な人、フラット張るとベースのネックが反っちゃうって人にはいいかもしれません。 音は良くも悪くもフラットの音です。使い始めはブライトな印象でしたが、弾き込めば落ち着きます。 【追記】 張ってからほぼ毎日弾いて約一年経ちます。新品の倍音が取れた、いわゆる死んだ状態でも音程感が損なわれることなく、さらに迫力が増したような印象です。 アコースティックからロックまで、まんべんなく馴染みます。 【追記2】 張ってから2年経過しました。 ライブにレコーディングに、セッションや練習まで酷使しています。 手入れはたまにクロスで拭く程度ですが錆びるようなこともなく、音の劣化も感じません。タフです。 【追記3】 張って3年と2日で2弦が切れました。 音の劣化は最後までなかったので満足です。
