2. Setup

2.1 Power Supply

The JF-14 pedal requires a DC 9V power supply. Ensure the power supply is center-negative and provides sufficient current for stable operation. Connect the power adapter to the DC 9V input jack located on the side of the pedal.

2.2 Connections

• Input (IN): Connect your guitar to the INPUT jack on the right side of the pedal using a standard 1/4-inch instrument cable.
• Output (OUT): Connect the OUTPUT jack on the left side of the pedal to your amplifier's input or other effects pedals in your signal chain using a standard 1/4-inch instrument cable.

3. Operating Instructions

The JF-14 features six control knobs and a footswitch for engaging/bypassing the effect.

3.1 Control Knobs

• LOW: Adjusts the low-frequency response (bass).
• MID: Adjusts the mid-range frequency response.
• HIGH: Adjusts the high-frequency response (treble).
• LEVEL: Controls the overall output volume of the pedal.
• VOICE: This crucial knob shapes the amplifier's character, ranging from a 'silverface' tone to a 'blackface' or 'tweed' sound. It interacts significantly with the MID knob.
• DRIVE: Adjusts the amount of gain/overdrive.

3.2 Footswitch

Press the footswitch to toggle the effect ON or OFF. A red LED indicator illuminates when the effect is active.

3.3 Tone Shaping Tips

Experiment with the VOICE and EQ (LOW, MID, HIGH) knobs to discover a wide range of tones. The VOICE knob is particularly interactive and can drastically alter the pedal's character. Adjusting the DRIVE knob will introduce more distortion, mimicking a cranked tube amplifier.

  • Verify that your guitar and amplifier are working correctly.
• Unwanted Noise/Hum:
  • Ensure you are using a regulated, isolated DC 9V power supply.
  • Check for faulty cables.
