GHOSTFIRE GS6 Guitar Pedal Power Supply - Compact High Current Unit

In this review of the GHOSTFIRE GS6 guitar pedal power supply, the bottom line is simple: this small, well-built unit is for players who need multiple isolated 9V outputs in a compact package and want a clean, durable box that travels well. The GS6's biggest selling point is its practical output mix - one 9V500mA port plus five 9V100mA ports - which covers a wide range of stompboxes while keeping weight and footprint to a minimum. The review examines noise, build, accessories, and where it fits on a pedalboard.

Key Features

• Compact and stylish design: The 4'in x 1.5'in x 1.2'in metal enclosure and eye-catching pattern make it easy to fit on small boards while adding a tidy visual touch.
• Multiple output mix: One 9V500mA and five 9V100mA outputs provide flexibility to power higher-draw pedals and several smaller pedals at once.
• Low noise operation: The unit is engineered to operate with stable, low noise so it does not noticeably add hum to most signal chains when placed correctly.
• Complete accessory kit: It ships with an 18V 1A center-negative AC adapter, six 60cm DC cables in straight and angled styles, and a user manual for a ready-to-use setup.
• Durable construction: Metal housing and quality components make it suitable for gigging musicians who need a reliable, roadworthy supply.

Who It's For

The GS6 is well suited to hobbyists, bedroom players, and gigging musicians who run a handful of pedals and want a compact power source with at least one higher-current output for an overdrive, boost, or a compact multi-effect. Its small size and included cables make it a solid option for modest pedalboards where space is limited.

Players requiring many high-current isolated outputs, integrated mounting hardware for large boards, or advanced switching and filtering features should look elsewhere. The GS6 is not presented as a large-floorboard power hub, so larger rigs with multiple 500mA+ pedals may outgrow its output mix.

Pros & Cons

Pros

• Compact metal case and attractive finish make it board-friendly and durable.
• Useful output combination with one 9V500mA port and five 9V100mA ports covers common pedal needs.
• Includes AC adapter and six DC cables so it is immediately usable out of the box.
• Generally low noise performance for clean signal chains when properly arranged.

Cons

• Some users report mixed experiences with noise on sensitive rigs, so careful placement and cable routing may be required.
• Output mix limits those with multiple high-draw pedals who need several 500mA or higher ports.
