Altero Custom Guitarsがサウンドプロデュース、監修を行い、KarDiaNのメインデザイナー"Toshikazu Kitada氏"が設計、デザインを担当した、滋賀の両傑によるペダルブランドが誕生しました。




Altero Custom Guitarsが今回デザインコンセプトに選んだのは ”Mahogany / マホガニー" です。

"Mahogany" が持つ表情豊かでリッチなトーンをディストーションで表現するためにKarDiaNのメインデザイナー北田氏と共に開発に挑みました。このペダルのコンセプトはディストーションペダルの盲点であるローゲインの再構築、そして対になるハイゲインでのエクストリーム感の共存、これらを備えることで誰も経験したことがないディストーションペダル "Mag" を作り上げることに成功しました。

最大ゲインで鳴らした際はハードリフを刻むことができるほど荒々しく歪み、エクストリームサウンドを体感することができます。ただ、通常このようなペダルはハイゲイン向けにチューニングされたフィルター処理のため、ローゲイン時には余分なコンプ感や、上下がバッサリ切り取られた情報量の少ない面白みに欠けたサウンドになってしまいます。そこで "Mag" はゲインコントロールに連動したフィルター回路の設計に挑みました。

"Gain" ツマミを11時の位置に、"Volume" ツマミを少し大きめに回したローゲインセッティングにしてみて下さい。まるでチューブスタックアンプのボリュームを上げた時のようなクリーンの存在感を感じながらも、奥底でギラッと歪むサウンドを味わうことができます。これはローゲイン時には適切なローカット量に、そして特に高域からプレゼンス領域までを必要十分量残す調整がなされているからです。

またこれらを支えるのは2つの特殊なトーンセクションです。 "Tone" は中・高域をフィルティングしながら音色を調整することができます、通常のトーンセクションと効果は似ていますが、高域は残したままサウンドを調整することができるのでエアー感やプレゼンス感が失われることがありません。そして "Presence" このツマミが注目のポイントです。Toneでは調整できないエアー感を含めた更に上の帯域を微細にコントロールすることが可能です。これによって実音を鳴らすアンプだけが持つ、キャビネットを通した空気を含むニュアンスをコントロールすることが可能です。

デザインはアルミ削り出し筐体を艶やかなヴァーミリオンカラーにアルマイトし、表面は高級感のある梨地加工を採用。レーザーによる刻印は高級感だけでなく、ステージでの使用において摩耗しない特性を持ちます。また、このペダルの由来である "Mahogany" の樹木をデザインとして刻み込みました。

Altero Custom Guitars has produced and supervised the sound, and KarDiaN's main designer, Toshikazu Kitada, has been in charge of the design.

The reason why we started this new brand is because we believe that as a guitar manufacturer, we want to create the best tone without sacrificing the original sound of the instrument. Even if we make a guitar that we are satisfied with, we don't want the pedals and amps that come after it to fall short of the sound we are aiming for. We started our pedal brand with this kind of professional spirit.

The pedals we make are designed to support the "natural sound of the guitar" as our focus. Therefore, we started from the point of leaving as much low as possible, which is useful for the acoustic characteristics of the guitar, and making the most of the sparkle of the strings, which is important for the sound. However, leaving too much of the lows and highs in a pedal can be inconvenient, especially when using an amplification circuit, and the sound itself can become muddy. Therefore, instead of using the circuitry alone to do the filtering, we used the filtering effect calculated from the cross-sectional area and dielectric constant of the wiring material, and designed it to produce a straight tone from the board. The appearance of the wood as a tree printed on the pedal surface expresses the respect for the old sound and the attitude to challenge the new sound through the pedal.


Altero Custom Guitars chose "Mahogany" for the design concept.

"We worked with Mr. Kitada, the main designer of KarDiaN, to create a distortion pedal that expresses the rich and expressive tone of Mahogany. The concept of this pedal was to reconstruct the low gain, which is a blind spot for distortion pedals, and to create a distortion pedal "Mag" that no one has ever experienced before.

When played at maximum gain, it distorts so wildly that you can carve hard riffs and experience an extreme sound. However, since such pedals are usually filtered and tuned for high gain, when played at low gain, you will get an extra comp feeling and a sound with little information, with the top and bottom cut off. This is why "Mag" took on the challenge of designing a filter circuit that works with the gain control.

Try setting the "Mag" to a low gain setting with the "Gain" knob at 11 o'clock and the "Volume" knob turned up a bit. You can feel the presence of the clean sound, just like when you turn up the volume on a tube stack amp, but you can also hear the distortion deep down. This is because the amp has been adjusted to have the right amount of low cut for low gain, and to leave just the right amount of distortion, especially in the high frequency range and presence.

These are supported by two special tone sections. The "Tone" section allows you to adjust the tone while filleting the mids and highs, similar to the effect of a normal tone section, but without losing the air and presence of the sound because the highs are left intact. The "Presence" knob is a key point of interest, as it allows you to finely control the upper range of the sound, including air, which cannot be adjusted with the Tone. This allows you to control the nuances that only a real sounding amp can have, including air through the cabinet.

The design features a machined aluminum chassis anodized in a glossy Vermilion color, with a high-grade pearl finish on the surface. The laser engraving not only gives the pedal a luxurious look, but also ensures that it will not wear out during stage use. The pedal's origin, the "Mahogany" tree, is also engraved into the design.
