JF-01 Vintage Overdrive Pedal

The JF-01 Vintage Overdrive Pedal by Joyo is a representation of the classic Tube Screamer, featuring a RC4558 chip. The overdrive effect is described as mellow, mild, and smooth, with nice sustain. The pedal is designed with a true bypass to minimize tone loss and is housed in an aluminum alloy casing with a stoving varnish finish.

Technical Specifications:
- Input Impedance: 500KΩ
- Output Impedance: 10KΩ
- Running Current: 7mA
- Power: 6F22 9V Battery/ DC 9V adapter (None included)
- Dimensions: 120(L)X 72(W)X 55(H) mm
- Weight: 290g

The pedal features three control functions: volume (output), drive (gain), and tone (treble boost or cut, focused around the 2-5k range). It can produce warm overtones when used as a clean volume boost and achieve a harsher distortion as the gain is increased.

The JF-01 Vintage Overdrive Pedal is suitable for guitarists looking for a classic overdriven tube amp sound and is well-regarded for its quality and affordability.

For optimal performance and to avoid unexpected noise, it is recommended to use a JOYO original power adapter or a reliable alternative that meets the current operating requirements of the pedal.
