The PSU 4x420mA PCB is a high-quality power supply design that combines four independent power supplies in one housing. This design ensures great sound quality without hum and distortion by eliminating ground loops.

Each section of the PCB is dedicated to a specific type of effect. Section 1 is designed for overdrive/distortion and compressors, which typically do not work well with a common power supply when used alongside digital effects. Section 2 is dedicated to modulations and other similar effects. Section 3 is specifically designed for digital effects, which can potentially interfere with other effects through the power bus. Finally, Section 4 is dedicated to amp loop effects, providing a separate section to avoid long ground loops.

With the PSU 4x420mA PCB, you can power even extensive sets of effects without worrying about ground loops or interference between different types of effects. The design ensures clean and reliable power for each section, resulting in optimal performance and sound quality.

In summary, the PSU 4x420mA PCB is a versatile and efficient power supply solution for guitar effects setups. Its four independent sections provide clean power to different types of effects, eliminating ground loops and interference. With this design, you can achieve great sound quality without hum or distortion.
