equipboard's Walrus Audio Pedalboard

The Walrus Audio Canvas Power 15 is a 15-output pedal power supply, and it sports some standout features as well as a sleek, compact, low-profile design. As of the time of writing, it is the second-largest Walrus pedal power supply from the Canvas series, between the Power 8 and the Power 22.

We were immediately impressed with the packaging and unboxing experience. Walrus certainly puts some thought into aesthetics, start to finish. In the package, you get 15 power cables and mounting brackets to help attach this unit to certain pedalboards. The power supply itself is really nice looking - almost a shame that it will sit out of sight underneath a board. The whole line of Walrus Canvas Power units feels rugged and well-built.

Feature-wise, it’s impressive. The 15 outputs provide ample 500mA 9V power. Two out of the 15 outputs are actually switchable between 9V, 12V, and 18V. This is a very small gripe, but the smaller Canvas Power 8 supply also has two variable voltage outputs, so it would have been nice to get three or four with this larger supply.

One of the smartest features that we would like to see more power supplies adopt is a power meter with 4 LEDs that spans from 10% to 100%, letting you know how much of the available power is being used. Yet another smart feature is a USB-C port to the left of the power outputs, so on top of powering your pedals you can charge a phone or tablet. Furthermore, each output has a green LED above it indicating that output is giving power, which is a handy reference when you’re looking at a mess of cables and pedals. These small but thoughtful features make this a standout pedal power supply.

In terms of operation, we encountered absolutely zero issues. Each output is isolated, and we experienced a silent and clean signal with every pedal we hooked up to it.

In terms of a pedalboard build, we slotted it under a Pedaltrain Nano MAX with no issue. Yes, we realize a Nano+ won’t fit 15 pedals, but we just wanted to prove how sleek this unit is. It’s just over 12 inches wide and only 1 inch tall. The power cables it includes have a 90-degree plug on the pedal end, which is another thoughtful, space-saving design detail from Walrus.

Bottom Line: It can be tough to select a power supply since their primary job is simple - deliver clean, isolated power to multiple pedals at once. The Walrus Audio Canvas Power series stands out with its well-thought-out features that go the extra mile, like the USB-C port and power consumption meter. Plus, 500mA power per output is very impressive. If your pedal collection has hit 8 pedals and you’re thinking about expanding, it is with little hesitation that we would recommend the investment in the Walrus Canvas Power 15.

The Walrus Canvas Power series of power supplies is impressive. They’re boutique quality, very well designed, sleek and compact, and very thoughtful in terms of features. The smallest of the pack is the Walrus Canvas Power 5, which will supply clean power to 5 of your precious pedals.

Obviously, this one is the most affordable of the bunch, and stripped of a few features compared to its larger siblings. It sports 5 isolated power outputs, delivering up to 500mA of power at 9v. The 5th outlet lets you switch between 9v/12v/18v in case one of your pedals needs or supports that.

Just like all the other Canvas Power Supplies, each output has a green LED that lights up to assure you that it’s delivering power out of that output - it’s a small detail but we love it. The 5 power cables it includes have a 90-degree plug on the pedal end, which is a thoughtful space-saving feature. Oh, and you also get mounting brackets to help with some pedalboard installations.

And speaking of installation, we love how compact the Canvas Power 5 is. It’s 5 inches (12.7 cm) wide, 2 inches (5 cm) deep, and 1 inch (2.5 cm) tall. That’s smaller and sleeker than many other 5-output pedal power supplies we’ve tried!

‌Note: You can order this for use in the US, UK, Australia, or Europe. Also, you can order it as the standalone power supply or the linkable version, which you can chain to another supply via 24v power link. This is a nice option to have as your pedal collection grows.

If you were to upgrade to the Walrus Canvas Power 8, you would get an LED power consumption meter, and a USB-C port to charge your phone. We really miss those features in the Power 5, and would have gladly paid a little more to have them.

Aside from those minor drawbacks, if you have a very compact board and have 5 pedals to power, this is a great little power supply. There was no unwanted noise, pops, cracks, or interference with all 5 outputs used at once. Clean power delivery all around in an attractive little package.

Bottom Line: It costs a little bit more than some other 5 output pedal power units, but honestly it’s worth it to get the little thoughtful details, the compact size, not to mention being able to deliver an ample 500mA of power.
