what is 529?

Mission Engineering 529 is the worlds most advanced guitar pedal power supply. If you are using the latest in digital effects pedals, modelers, multi-effects or wireless systems, you should be using the most up to date power supplies to power them.

Traditional power supplies are based on old designs that have been around for decades. 529 leverages technology from computing and automotive applications to make modern power supplies that are smaller, lighter and more powerful.

Mission 529 supercharges your pedal board with state-of-the-art features such as USB Power Delivery and wireless rechargeable Lithium Polymer batteries.

Some digital modelers require more than 100 times the power of analog effects pedals. The 529M provides programmable voltage outputs up to 20V and a massive 5000mA of current suitable for the most power-hungry devices such as the Line 6 HX Effects and NeuralDSP Quad Cortex.

Check out the Mission 529 models and get more power and more capabilities with the worlds most advanced guitar pedal power supplies.

more power, less noise

Good isolation in pedal board power supplies is very important as it prevents noise generated by digital devices passing into the audio path. If you have ever connected up an effect pedal and been greeted by unpleasant noises, you’ll know what we mean. If noise from the power circuit makes its way into the audio path, you’ll hear it through your amp as hiss, hum, whining or clicking. When using 529 with a DC battery source, there is no AC noise such as 60 cycle hum to worry about. Isolated outputs and extensive filtering on the switching side make the 529 one of the quietest supplies available.


The 529i powers your entire pedalboard from an internal rechargeable Lithium battery. With 2 x 500mA and 6 x 300mA 9V fully isolated outputs, the 529i will power your pedalboard for 4 hours or more on a single charge. Recharge using the included 12V power supply, or from any USB charger.

The isolated 5V USB output can be used to simultaneously charge mobile devices, ideal if you use a phone or tablet for set lists, scores or lyrics. The included voltage doubler cable allows two outputs to be used in series to power 18V pedals. All 9V outputs include short circuit and over-current protection. LED indication displays input and output power active, charge state, and fault condition. There’s even a power switch to turn all your pedals on or off with a single touch.


Small, light and ultra-quiet, the Mission 529 is the world’s first USB isolated power supply for small pedalboards. 529 can power your pedals with the included wall power supply, but the beauty is that you can switch this out for almost any rechargeable power-bank, phone charger, computer, or even a car USB port.

With four isolated 150mA outputs for standard pedals, plus one 500mA output for high power devices, 529 gives you the flexibility to switch between wall and battery power on demand.

At just 4″ long and weighing only 4oz, the 529 is one of the lightest power supplies available. It easily fits under the smallest of pedalboards, such as the Pedaltrain Nano.


The 529M is the world’s most powerful pedalboard power supply.

Using the very latest in USB Power Delivery technology, 529M works with a USB-PD charger or rechargeable power bank to provide a single high current (3000mA) output with five selectable voltages. Used with a suitable power bank or wall charger, the 529M delivers up to 60W of power to modern digital modelers and multi-effects from a tiny, lightweight device about the size of a 9V battery and weighing just one ounce.

529M can be used with a daisy chain cable to provide a stable 9V to large numbers of analog effects or as a single output power supply for high current devices such as the Line 6 HX series and NeuralDSP Quad Cortex.

WHAT users SAY

I was wall-wart/daisy-chaining power before, and pedal noise made my pedals almost unusable. This made my pedal train so quiet that I’m actually hearing all the nuances of the pedal effects that I’d never heard before! No wires running to the wall are a HUGE bonus. 

What a brilliant little product! I have no idea how it does what it does, but it works like a charm and was a great solution for my small pedal array. Highly recommended!

I was putting up with the 60-cycle hum for a long time because the thought of changing out 9V batteries for each one was causing me to have them all cheaply daisy-chained together from a single plug for convenience. Finally, I broke down and bought this and I’m thrilled.

Works exactly as advertised. Very sleek in person. You won’t regret your purchase.
