A Power Supply Designed for the DigiTech Ecosystem
Designed to support the brand's multi-effects and pedals, this power supply meets the common needs of DigiTech users: stable voltage, sufficient current, and easy setup without adjustments. It is an ideal solution to replace a lost adapter or to have a dedicated power supply unit for a pedalboard.
Intended Use and Target Musicians
This power supply is aimed at guitarists and bassists who use an RP 55, a DigiTech X-Series pedal, or a HardWire pedal and who seek a reliable mains power source for rehearsals, recording, or live performance. The 100-240 V input range also facilitates use in different countries (with the appropriate plug adapter if necessary).
Stability, Current, and Polarity: Key Points to Check
The stabilized voltage helps reduce unpredictable behavior caused by irregular power supply. With 300 mA, it delivers the necessary current to compatible devices, and its center negative polarity ensures compliance with DigiTech equipment designed for this polarity. Before connecting, always verify that your gear accepts 9.6V DC and center negative polarity.
