Walrus Audio Harvest Series Canvas Power HP Plus Pedalboard Power Supply

The Walrus Audio Harvest Series Canvas Power HP Plus brings high-capacity, low-noise performance to modern hybrid rigs, delivering stable power for everything from multi-effects units to demanding analog pedals. Its combination of two 3A high-current outputs, seven isolated 9V outputs and a 9/12/18V variable-voltage channel supports complex boards with clean, interference-free operation. An ultra-slim 1.2" enclosure slides beneath nearly any pedalboard, while a modern switch-mode architecture and heavy filtering ensure quiet performance—even with sensitive digital or gain-heavy analog devices. Built for players who need dependable power across large or power-hungry setups, the HP Plus keeps your entire rig running smoothly and consistently.

Clean, Isolated Outputs for Silent Performance

The Canvas Power HP Plus anchors pedalboards with seven isolated 9V outputs rated at 500mA each, plus two high-powered 3A outputs that switch between 9V and 12V for current-intensive gear like modelers or multi-effects processors. Every output uses heavily filtered switch-mode circuitry to eliminate hum and electrical noise, ensuring your signal chain stays clean and responsive. Whether feeding reverbs, high-gain drives, time-based effects or amp-modeling units, the Canvas Power HP Plus maintains clarity and definition across your entire board.

Flexible Voltage Options for Modern Rigs

For pedals that require more than standard 9V operation, the Canvas Power HP Plus includes a variable-voltage output selectable at 9V, 12V or 18V—ideal for preamps, overdrives or boutique units that respond differently at higher headroom. The two 3A outputs also offer switchable 9V/12V operation, accommodating devices with heavier current demands. A built-in USB-C port provides convenient charging for wireless systems or accessories, making the Canvas Power HP Plus adaptable to a wide range of analog and digital workflows.

Pedalboard-Friendly Form Factor With Touring Durability

At only 1.2" tall, the Canvas Power HP Plus mounts easily under most pedalboards using the included universal brackets, while low-profile cables with both straight and right-angle plugs streamline routing in tight spaces. Each output features dedicated LED status indicators for quick visual monitoring, and the unit’s rugged construction is designed to withstand touring wear, frequent transport and heavy nightly use. Whether building a compact pro board or powering an expansive hybrid rig, the HP Plus delivers stable, quiet performance built for real-world gigging.

High-Capacity Power for Demanding Setups

For musicians who rely on large or power-intensive pedalboards, the Walrus Audio Harvest Series Canvas Power HP Plus offers a smart balance of high output, low noise and flexible voltage options. Its slim build, isolated outputs and robust filtering make it essential for maintaining clean tone across complex rigs. With reliable performance at home, in the studio or on tour, the Canvas Power HP Plus ensures your pedals and processors stay powered safely and consistently—so your focus stays on the music.
