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.
