1. Introduction
The JOYO Vintage Overdrive Pedal (JF-01) is designed to provide classic overdrive tones for electric guitars. It features an RC4558 chip, replicating the sound characteristics of the renowned TS808. This pedal is engineered to deliver warm overtones at lower volumes, functioning as a clean volume boost, and can produce a more pronounced distortion as the gain is increased. Its true bypass design ensures minimal tone loss and maintains a clean signal path when the effect is disengaged.

5. Power Supply
The JOYO Vintage Overdrive Pedal requires a DC 9V power source. It can be powered by either a 6F22 battery or a DC 9V power adapter (not included). For optimal performance and to avoid unexpected noise, it is recommended to use a JOYO original power adapter or another reliable brand that meets the specified working current requirements (7mA).
Important Note: Always ensure the power adapter is center negative. Using an incorrect power supply can damage the pedal and void the warranty.
