Overview

The SubZero PS09 is a utility device aimed at guitarists and bassists who use complex pedalboard setups. By consolidating power distribution into a single unit, it eliminates the necessity for individual extension leads and bulky 'wall-wart' adapters. The unit is designed to sit directly on or beneath a pedalboard, providing a centralised hub for DC power distribution.

Functionality and Key Features

The primary feature of the PS09 is its versatility in voltage output. While most standard stompboxes, such as the Boss NS-2 Noise Suppressor or the Behringer UC200 Ultra Chorus, require a standard 9V supply, certain high-headroom or specialised pedals require 12V or 18V. The PS09 provides dedicated ports for these variations, ensuring compatibility with a wide range of gear including the Digitech Whammy Ricochet or the Fender Hammertone Flanger.

The unit comes supplied with a comprehensive set of DC cables and adapters, allowing users to connect their pedals immediately upon unboxing. Its layout is designed to facilitate clean cable management, reducing the 'mess' often associated with large effects chains.

Sound and Character

As a power supply, the PS09 does not have a 'sound' in the traditional sense of an effects pedal like the Electro Harmonix Big Muff. Instead, its character is defined by its reliability and its ability to provide consistent voltage. By replacing individual batteries, which can lose voltage over time and cause circuit sag, the PS09 ensures that digital pedals like the Boss DD-3T Digital Delay operate at their peak performance levels without unexpected shutdowns or signal degradation.

Target Audience

This unit is particularly suited for gigging musicians and studio players who have outgrown basic daisy-chain power solutions. It is an entry-level professional solution for those who own a variety of pedal brands and types. Because it supports multiple voltages, it is an ideal choice for players who mix standard 9V pedals with more demanding units like specialized wahs or expression controllers.

Comparison to Alternatives

Compared to basic daisy-chain cables, the PS09 offers significantly more flexibility due to its 12V and 18V outputs. In terms of price, it sits in a competitive bracket, typically retailing around £40, making it more accessible than many boutique isolated power supplies. While it provides more outputs than standard entry-level bricks, users should always check the total milliampere draw of their specific pedals to ensure the unit meets their total current requirements.
