Effects pedals and current
April 30, 2014 by

Definitely mA-ybe

Effects pedals need to be powered at the right voltage, and they need the right current to work properly too, so picking the right PSU to power your chain is important.

It’d be great if you could use batteries every time, but they’re expensive, and you can’t rely on them not running out when you’re playing a gig or recording unless they’re fresh.

I’m sure Jonny Greenwood powers every pedal with a new battery every time, but he can afford to put Duracell’s kids through college – most of us can’t.

If you’re looking for one PSU to power all your pedals (and you’re happy you know what polarity they need and if they need AC or DC) you need to add up how much the current they’ll use.

Power supplies from the future

When designing new MyVolts products, one of the main objectives of the design team has been to immerse ourselves in the world of USB power.

As product designers from different backgrounds, it has been fundamental for us to learn about the development of the USB, and what the future holds for it. For nearly a year, we have worked together to fully understand all the techy details about USB, from the physical shapes and sizes of the different types of USB connectors (hardware) to the technical capabilities of each version of USB. Essentially, we want to have a knowledge level of expert of what already exists in the USB world and what is to come, so that we can develop the best possible MyVolts power delivery products now and in the future.

DIN connectors all in a row

What’s that DIN?

I sometimes get asked about how to power a device with a power input that isn’t the the regular barrel-type power input we’re all used to.
You probably know what I’m taking about: you may have seen a device, like an older external hard drive or other storage device, with an unusually-shaped power input, with a number of inputs, designed to accept a power connector with a number of pins. Homething like this:

Buzz kill

Occasionally when something changes in a music gear setup, you can experience buzz or hum. A little is tolerable of course – no setup is 100% perfect, and a little imperfection can add warmth and realness to your sound.
But sometimes it’s intolerable. It can happen with effects pedals, mini amps, keyboards, MIDI controllers, or wireless signal senders and receivers – and really any other gear too.
Tempting as it may be, don’t immediately blame the power adaptor!

A brief history of DC power supplies

Agriculture; the wheel; metallurgy; the Guttenberg printing press… These are all watershed moments in human history. Our species has been transformed several times by technological breakthroughs. And the discovery of electricity has proved no less transformative than the milestones listed above.

Not long after the industrial revolution, scientists began to discover new applications for electricity. But it wasn’t until the 20th Century that electricity made its way into our homes for the first time. At the outset, the only electrical outlet available was a pendant-type light socket hanging from the ceiling (much like we still have today). Then, in 1903 a man named Henry Hubbell patented a modular light fitting which enabled the attachment of other electrical devices: “so that electrical power in buildings may be utilised by persons having no electrical skill”.
