JOYO Dr.J Series D50 Tube Overdrive Pedal Instruction Manual

Introduction

The JOYO Dr.J Series D50 Tube Overdrive Pedal is designed to deliver the characteristic tone of overdriven tube amplifiers. It provides clear, transparent, warm, and natural tones with a dynamic feel and minimal compression. This pedal is built with a robust full metal housing and features a true bypass design to minimize tone loss when disengaged.

Setup

Power Supply Connection

The D50 pedal requires a DC 9V, 800mA power supply with a central negative polarity. The power supply is not included with the pedal. Ensure the correct polarity and voltage to prevent damage.

Maintenance

The D50 pedal features an extraordinary solid metal housing, designed for durability. To maintain its condition, keep the pedal clean and avoid exposing it to extreme temperatures or moisture. Always disconnect the power supply when not in use for extended periods.

Troubleshooting

No Sound: Check all cable connections (guitar to input, output to amplifier). Ensure the power supply is correctly connected and functioning.
Unwanted Noise: Verify that the power supply meets the specified requirements (DC 9V, 800mA, central negative). Ensure proper grounding of your equipment.
Tone Loss: The pedal features true bypass, which minimizes tone loss when off. If tone loss occurs when the pedal is engaged, adjust the tone controls (LOW, HIGH) and experiment with the CLIP switch settings.
