The Truetone 1-Spot Pro CS7 is a compact, lightweight, versatile power supply that can power most pedals on the market—whether they are 9, 12 or 18V.

With seven outputs you can power a pretty good sized board without the power unit taking up a massive amount of space on or under your board.

The power input is switchable for worldwide voltage. That means as long as you’ve got the right plug on the end of your lead you’re set wherever the gig takes you.

Why should you care about the tech behind the box? Technically, it’s switching power supply technology, which is very different than what anyone has ever put inside a power brick. Normally, you would find just a big transformer and a handful of small electronic components inside a power brick… old tech that hasn’t changed in decades and has a lot of limitations. Truetone took the same triple filtered switching power supply technology found in their famous 1 SPOT and scaled it up to make the 1 SPOT Pro model range. With much more space to work with, Truetone were able to completely eliminate noise, provide total electrical isolation between outputs, create multiple voltages, and still give you the ability to use it anywhere in the world.

A major benefit of using a switching power supply is that it can handle far more current (power being pulled out of it) than any transformer-based power supply. Although Truetone had to put power rating labels on each output to satisfy certification agencies (yes, they actually certified these, unlike most companies), the outputs can generally handle far more than the label shows. For example, you can connect a 300mA pedal to a 200mA output, without causing any problems. With a transformer-based power supply, you can’t get away with that.

The important thing is to not exceed the total of all the labels. With a CS7, the output labels add up to 1900mA total. That means the total current draw of all your pedals should be less than 1900mA. That total current rating is roughly double the current load of the most common power brick, for a lot less money.

See the images for how the outputs are arranged.

We are an online store only, so your new pedal has never been demoed on a shop floor or been out on display. We do though test all pedals (and any power supplies where included with pedals) before we send them out to hopefully minimise any hassles of faulty pedals on delivery.

We use recycled materials where possible for our packaging, and all our energy is from renewable sources. Check out our environmental page.
