Opting for a good canvas is an important decision that often makes or breaks otherwise great works of art, whether that’s literal paintings or the sonic art you make with pedals and effects. And just like a low-quality canvas can dull brilliant colors, a low-quality power supply can dull your tone. Enter Walrus Audio’s collection of sleek and slim Canvas Power supplies! They bring clean, isolated power to your rig with little noise. Players can choose small, medium, large, or extra-large Canvas Power options and power anywhere from five to 22 pedals, and each size has one or more variable output(s) for pedals with picky voltage demands. Smaller units like the Canvas Power 5 and Canvas Power 8 are perfect for compact rigs, hobbyists, and beginners. Larger Canvas Power 15- and 22-outlet options give touring professionals and pedal enthusiasts lots of flexibility and tools. Whether you go big or small in your choice of a Canvas Power supply, Sweetwater’s pedalboard pros know you’ll appreciate that these power supplies mount almost effortlessly to various popular pedalboard platforms.

Walrus audio Power supply

By CHARLES D. from MONTPELIER, VA

This is a boring piece of kit right here Folks! But it does the job perfectly! I was quite shocked by how small it is and with so many outputs(15) it powers all my thangs! As always Jason Mathis did a great job as do all the folks at Sweetwater! Thanks to all who were involved!

Perfect

By Sweetwater Customer

Great design, flawless function, includes all the cables you need. Knocked it out of the park

just right

By Daniel B. from PHOENIX, AZ

I usually do not write reviews, but I thought that this was worth it. My old supply died, so I had to get something. This looked good. It was even better in person. Mechanically, it was a great shape and easy to mount. It also came with good power cables. The large current capability of all channels meant I did not have to think about running the right power to the right pedal. Finally, it was less noisy than the old one. I get that it is not cheap, but it really is nice.

Love it

By DTM1864 from Bronx, NY

My previous power supply was not an isolated power supply; my rig was noisy. The Canvas Power 15 is isolated and my mini Marshall Plexi rig is nice and quiet; whether the Decimator Noise Suppressor is on or off. The Power 15 is just what I needed. Great packaging, small footprint and very good build quality. I recommend it.

Great Canvas power supply

By Joey C. from TX

I love everything about this power supply. It provides isolated power to my pedals so there is less floor noise. It fits nicely under the pedalboard and is super light that it doesn't add to the weight. I also like that each output provides 500mA of power which great for awesome Strymon pedals.

Awesome power brick

By DAS from Washington DC

Picked this up for a great deal on Black Friday and couldn't be happier with it. It's super low profile, light and versatile with the variable voltage channels it. has. I put mine under a temple audio trio 28 board mounting with 16mm M3 screws and washers. The mounting brackets it comes with I guess are ok but didn't really fit my needs and I didn't use them. Power is very clean, my signal noise I used to get with my One spot is all gone.

Real good power supply

By Mike C. from The Great White North
Music Background: 52 years of Playing, Recording and working on guitars

Works as expected. The brackets did not fit the pedal board I use but a little modification on the brackets worked well. Nice power supply. Powers all my pedals perfectly.

Perfect power supply for temple audio

By Sweetwater Customer

Had a voodoo labs and a true tone that worked great for years but were to big for a temple audio board. Now this one fits perfectly and all ports are high powered so no figuring out were to plug my digital pedals in

Works Perfectly

By TYSON from Texas
Music Background: Semi-professional, part time touring musician

Bought this so I could power ALL my pedals with their different power needs off of one source. Works like a charm for 6 9v pedals, 1 12v pedal, and 1 18v pedal, including my Shure wireless guitar system. Used it for a few months now and zero issues. Does what it claims, and easy to assemble and work with.

This works great it's amazing how small it is.

Great power supply

By Matthew D. from North eastern United States
Music Background: Playing guitar for 5 years

It's awesome. No noise. Sleek design lets you easily affix to your pedal board. 13 9v and 2 ( 9v,12v, 18v) adjustable outputs. Comes with everything you need except the board and pedals. My first walrus product but definitely not my last. And I got it about 4 days after ordering during the new years weekend. And even got a call from my sales engineer the day it arrived to see if I had any concerns or problems. Thanks Sweetwater.

Awesome Power Supply

By Sweetwater Customer

Recently made some upgrades to my board and needed a bigger power supply. This has been a perfect addition to my board. Looks great and runs all my pedals while reducing the noise. Would highly recommend. 10/10.

This is THE pedal power supply.

By El p. from FL

This is it folks. The attention to detail on this thing is impressive. With the power brick away from the unit I was able to easily and comfortably find an ideal design for my board. The 500ma on each port makes it a no brainer to route the cables, and the short cables make it so clean and compact. And boy is this thing pretty - even the box it came with! At the moment only drawing about 15%. Even with a microcosm this power supply can power another 13 pedals while taking a nap.

Brilliant, scalable, beautiful, effective. Walrus you knocked it out of the park. Now make the real canvas (the pedalboard, the perfect one).

Great power supply

By SPK from NJ

This delivers quiet, clean power. It's really low-profile, so it easily fits under my board, and it's light too. The only thing I'd change is the main power input is the same as the pedal outputs, and I feel like it could get pulled out easily. I wish it were a beefier connector like a C13.

No more white noise!

By Terry P. from Holland, MI.
Music Background: Bass

While using in-ear-monitors @ church I could always hear white noise in my bass pedal board. To make it worse, the noise always seem to change slightly from week to week and from pedal to pedal. Using a Boss noise suppressor , and a hum cancelling ground isolator did nothing to help the constant hum. I thought I tried everything else, I might as well try a new HIGH quality power supply. Problem solved!!! I threw that MXR DC brick away! the Walrus Audio Canvas power supply solved the white noise problems and the other issues I was having with individual pedals. Well worth the money.

So glad I went with Canvas, perfect for the nano max

By StevieV from Las Vegas, NV

Purchase this, hoping to power a load of mini pedals, it fits perfectly under the pedal train nano max. It's still has the two variable slots open and available and I like that I still have USB charging that I can easily access. It's nice and slim and easily fits. Appears to be well built, looks fantastic and I appreciate the included mounting brackets, which worked flawlessly.

Walrus Audio Does It Again

By Ryan B. from CALIFORNIA, MD

So, full disclosure: This is my first pro-level isolated power supply for a pedalboard build. That said, its closest competition was the Cioks line of power supplies. As soon as Walrus's Canvas series of power supplies was announced, I knew this was the one.

My requirements were as follows: At least 10 isolated outputs, slim / easy to mount to a board, enough power between ports to power a Line 6 HX Effects, and overall power use LEDs would be nice, but not necessary.

The Cioks power supplies did a lot of these things, but I trust Walrus as a brand and I like the form-factor on these better.

And I gotta say: I am SO glad that I picked this one! The size is great at just over 12" long by 2" wide and 1" thick. It comes with Pedaltrain style brackets (so you don't need to buy them separately) and even if it didn't, the thing weights under a pound and could easily mount anywhere on your pedalboard with velcro or dual-lock.

I got the Voodoo Labs Doubler Cable so I could double 2 of the 500 mA ports to my HX Effects and it works great! Do note though: If you're using a doubler to supply power to a power hungry pedal, you're going to want to use the regular 500 mA ports and NOT the 2 switchable ones that do 9, 12, or 18 volts. Even though I had both ports set to 9 volts, when I tried to power the HX Effects from them the power just flickered on and then it cut out shortly after. Something tells me those ports aren't designed to be doubled.

Overall, this power supply is awesome! Feels premium, is lightweight but durable, and I like the design. I'll definitely be linking more in the future if I need more power.

Thanks, Walrus Audio!

Canvas 15 Power Supply

By Bill from Tucson AZ
Music Background: Just love to play!

Great product. Comes with mounting hardware and plenty of power cables. Super quiet power delivered to the pedals. Plenty of mAh to every pedal so no problems with some of those pesky pedals that like plenty of power.

The Canvas 15 is really low profile so no issues fitting in the pedal board.

Good Luck with the toggle switches...

By Sweetwater Customer from TX

Horrible design using toggle switches to change output voltage and risking damaging your pedals. Just an advice, plug to those outlet only pedals that can take the maximum output voltage.

Awesomeness

By Sweetwater Customer

So far so good! Just got it today and used it to replace two Aetos power supplies as well as two wall warts since the Aetos was limited to 300MA. Powering 13 pedals, including a Chroma Console, DL4 MKII and a Boss RV-500 and it is still under 10% usage! It's nice and thin, though I feel the mounting options could have been more thorough. Used the supplied brackets and zip ties to connect it to my Temple Audio board. I was surprised how big the box was! Was very close to going with a CIOKS or Gig Rig system and happy that this came along.

Exactly what I needed

By Seth

I replace two CS7's with this. Now my entire board is powered perfectly by one thing. The CS7's also wouldn't power the Friedman IR-X with a current doubler cable for whatever reason. The Walrus does it just fine. It's much lighter and more compact too and mounts seamlessly under a pedal train. Really happy with it.
