Is the JF-01 an overdrive pedal or a distortion pedal? Is it suitable for live use?

The JF-01 is a vintage-style overdrive for warm rhythm crunch and smooth lead boost, not aggressive high-gain metal distortion. Its aluminum alloy housing fits pedalboards; use a regulated 9V supply or fresh battery for stable performance.

What power supply should I use?

Use a 6F22 9V battery or compatible DC 9V pedal adapter. Battery/adapter not included. Check voltage and polarity before use; incompatible power may affect performance or damage the pedal. For best results, use a regulated, isolated power supply.

Why is there noise, hum, or squealing?

Unwanted noise may come from the power supply, cables, guitar pickups, amplifier gain, or the full pedal chain. For testing, use a fresh 9V battery or regulated 9V adapter, good instrument cables, and connect only Guitar → Pedal → Amp first.

What should I check if the setup does not work as expected?

Check the power source, polarity, battery condition, input/output connection, cable quality, and knob settings. If you need any help with setup or use, send us a message through the Amazon order page.

Why does the tone sound different from what I expected?

Overdrive tone is affected by your guitar, pickups, amp, cable, power supply, and playing style. Tone preference is subjective and may vary by setup. The JF-01 is designed for vintage-style overdrive rather than extreme high-gain distortion.
