主な特徴

  • Rich, Organic Sustain: Provides high-fidelity sustain that enhances every note and chord.
  • Multi-Layering Capability: Creates up to three simultaneous layers of sustain with natural decay.
  • Dynamic Triggering: Layers can be engaged via footswitch or automatically triggered by playing dynamics.
  • 直感的なコントロール: Features Mix, Trig, Attack, and Decay knobs for precise sound shaping.
  • Sub Octave Switch: Adds a subterranean octave to one or more layers for a deeper sound.
  • 高度なプログラミング: Offers customization options for modulation intensity, delay time, diffusion, and more.
  • External Control Options: Supports external sustain pedals or switches (e.g., MXR Split + Tap) and expression pedals.
  • 多彩な接続性: Supports Stereo Input, Stereo Output, and Dry/Wet Split modes.

設定

Follow these steps to connect your MXR M307 pedal to your guitar and amplifier。

  1. 電源接続: Connect a 9V DC power supply (center negative, 300mA minimum) to the power input jack on the side of the pedal.
  2. 入力接続: 標準の 1/4 インチ楽器ケーブルを使用して、ギターをペダルの右側にある「IN」ジャックに接続します。
  3. 出力接続: ペダルの左側にある「OUT」ジャックを amp標準の 1/4 インチ機器ケーブルを使用して、lifier の入力に接続します。
  4. Optional External Control: For advanced functionality, connect an expression pedal or external footswitch to the "CTR" jack on the left side.

  1. CTR Jack: Used to connect an expression pedal or external footswitch, or to send a dry output signal when using Dry/Wet Split mode (see Advanced Operation).
  2. フットスイッチ: Governs the creation and deletion of sustain layers.
    • Pressing the footswitch engages a layer.
    • Holding the footswitch holds a layer indefinitely until released.
    • Upon release, the layer fades out according to the 減衰 設定。
    • A double tap clears all layers and bypasses the pedal.
  3. ATTACKノブ: Adjusts the fade-in time of each layer.
  4. MIXノブ: Controls the level of the wet signal (the volume of your layers).
  5. SINGLE Button: Limits the sustain effect to a single layer. By default, there are three simultaneous layers that can overlap. When シングル is engaged, only one layer will be active at a time.
  6. TRIG Knob: Sets the sensitivity for auto-triggering layers with your pick attacks.
    • いつ TRIG is in the OFF position (fully counter-clockwise), auto-triggering is disabled, and only the footswitch can activate layers.
    • の TRIG LED is red by default when auto-triggering is enabled; when the input signal exceeds the set threshold, the TRIG LED 緑に変わります。
    • For a layer to be triggered, the signal must exceed the threshold (i.e., the TRIG LED is green), and the pedal must detect a pick attack.
  7. DECAYノブ: Sets the fade-out time of the layers, mimicking natural string vibrations by decaying high frequencies first.
  8. SUB OCT Switch: Engages a sub-octave effect, taking one or more of your layers down an octave for a deeper, subterranean sound.

Layering Mechanics

  • The pedal supports up to three active layers, each indicated by its own mini LED.
  • Layers can be triggered manually by the footswitch or automatically based on your playing dynamics (controlled by the TRIG つまみ）。
  • To hold a layer with the footswitch: Play a note or chord, then press and hold the footswitch. Release to allow the layer to fade.
  • To auto-trigger layers: Adjust the TRIG knob to set the sensitivity. Layers will be created in response to your attack.
  • Combining methods: With シングル mode disengaged, you can hold a layer with the footswitch and then auto-trigger additional layers over it.

高度な操作

The MXR M307 offers extensive customization through its programming functions. These allow you to adjust parameters beyond the front panel controls.

  • プログラム可能なパラメータ： Adjust modulation intensity, delay time, diffusion, and other advanced settings. Refer to the full MXR M307 manual (available online) for detailed programming instructions.
  • External Sustain/Tap Control: Use a keyboard sustain pedal or an off-board switch (e.g., MXR Split + Tap) connected to the クリック率 jack to trigger layers.
  • エクスプレッションペダルの統合: エクスプレッションペダルを クリック率 jack to blend setting configurations, such as with the Volume(X) 8 Pedal.
  • Stereo and Dry/Wet Modes: The pedal supports Stereo Input, Stereo Output, and Dry/Wet Split modes for enhanced routing flexibility. Consult the comprehensive manual for setup details on these modes.

メンテナンス

  • クリーニング： ペダルの外側を拭く際は、柔らかく乾いた布をご使用ください。研磨剤入りの洗剤や溶剤は使用しないでください。
  • 電源： Always use a regulated 9V DC power supply with a center-negative polarity and a minimum current rating of 300mA. Using an incorrect power supply can damage the unit and void the warranty.
  • ストレージ： ペダルを使用しないときは、直射日光や極端な温度を避け、涼しく乾燥した場所に保管してください。
  • ケーブル接続: Ensure all cables are securely connected. Periodically check cables for wear and tear.

トラブルシューティング

問題考えられる原因解決
音が出ない、または信号が弱い。Incorrect cable connections, faulty cables, incorrect power supply, pedal in bypass mode.
  • Verify all instrument and power cables are correctly and securely connected.
  • さまざまなケーブルでテストします。
  • Ensure the power supply meets the 9V DC, center-negative, 300mA minimum specification.
  • Double-tap the footswitch to ensure the pedal is engaged (not in bypass).
Layers are not triggering automatically.TRIG knob set to OFF, insufficient input signal, SINGLE mode engaged.
  • 回転する TRIG knob clockwise from the OFF position to increase sensitivity.
  • Ensure your guitar's output signal is strong enough to exceed the trigger threshold (TRIG LED should turn green).
  • を解除します シングル button if you intend to create multiple layers.
Layers fade too quickly or too slowly.DECAY knob setting.調整する 減衰 knob to achieve the desired fade-out time.
