The world's first low profile power brick with switching power supply technology.
The 1 SPOT Pro Story
For many years, Truetone has made musicians’ lives easier with the 1 SPOT, the original compact pedalboard power supply. It works so well that a lot of musicians never felt the need to get one of those brick-style power supplies, and we here at Truetone didn’t see the need for those either, even though they were quite popular. Bob Weil, founder of Truetone, explains:
“A lot of people over the years had told us that we should make a power brick. Even some of my own staff urged me to do it, but I didn’t want to for two reasons. First, I knew the 1 SPOT could power just about every pedal out there, so I didn’t see the need. Second, I didn’t want to make just another knock-off of someone else’s power brick. If we were going to make one, we were going to do it our way and have features that nobody else could offer. As pedal designs changed and it became more common for digital pedals to require isolation and for others to need something other than 9Vdc, I finally saw a reason for us to design a power brick.”
“It took 3 years and lots of experimentation, but we were finally able to design a 1 SPOT Pro, using our own proprietary technology to give musicians all the features they need for today’s pedalboards. The original 1 SPOT still works great for most musicians, but for those who need more power and versatility, the 1 SPOT Pro fills the need perfectly.”
Introducing the Low-Profile CS6
Following on the tremendous success of the 1 SPOT Pro CS7 and CS12, Truetone presents the most powerful slim line power supply in its class, the 1 SPOT Pro CS6. Utilizing the energy efficient technology found in all 1 SPOT’s, the CS6 is the first low-profile power brick to be able to put out up to 1600mA of pure, silent power.
Just like its bigger brothers in the 1 SPOT Pro line, the CS6 has a variety of DC voltages available to power just about any pedal on the market. Each output is completely isolated, regulated and filtered, eliminating crosstalk and noise. With no big transformer to hinder their performance, proximity noise is not an issue with any 1 SPOT Pro.
The low-profile design of the 1 SPOT Pro CS6 allows it to be mounted under flat pedalboards like the Pedaltrain® Nano and Metro series. However, the compact design is also perfect for mounting on top of pedalboards, serving the dual role of a power supply and pedal riser.
1 SPOT Pro Features (All Models)
1 SPOT Technology
1 SPOT Technology… what does that mean and why should I care? 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. We took the same switching power supply technology found in our famous 1 SPOT and scaled it up to make the 1 SPOT Pro models. With much more space to work with, we 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 we had to put power rating labels on each output to satisfy certification agencies (yes, we 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 CS6, the output labels add up to 1600mA total. That means the total current draw of all your pedals should be less than 1600mA. That total current rating is much higher than any other low profile power brick... and it cost less too!

Rugged Steel housing
If you’re a touring musician, or even if you just play at the local pub regularly, you know how important it is to have road-worthy gear. No worries with the 1 SPOT Pro. The housing is all steel, with cleverly designed vents that should keep out the accidental beer spill, should that ever happen. And the CS6 is completely sealed for extra protection.
Since pioneering the first switching power supply for musicians, the original 1 SPOT, we’ve gained many years of experience in creating very low noise power for pedals. When we started designing the 1 SPOT Pro, the first multiple output switching power supply, we worried a lot about how to eliminate noise completely. Isolation is part of the solution to noise elimination, but not all of it. Each output is galvanically isolated from the other to help give you pure, clean, noise-free operation of your pedals. However, we also provided an additional layer of pure analog regulation, taking advantage of the greater ability of analog circuits to provide the highest possible suppression of in-band audio noise. There is an artistry involved in these designs, and it’s come at the price of decades of hard work. But all of this put together is what we call Pure Isolation.
Prior to the 1 SPOT, musicians either used one linear power supply (a.k.a. wall wart) per pedal, or used batteries. Both solutions for powering pedals were very inefficient with energy, with batteries also contributing greatly to the toxic waste stream.
In 2000, we pioneered the use of switching power supply technology to alleviate this condition in an economically-, energy- and environmentally-conservative way. The 1 SPOT power supply was designed to replace many such external power supplies and/or batteries simultaneously. It provided plenty of power with a very low noise level to successfully meet the needs of musicians.
By offering musicians a solution that was more cost effective and energy efficient, and moving the market away from linear transformer-based power supplies to switching power supplies, Truetone has caused the saving of thousands of watt-hours per musician per year.
Utilizing a more comprehensive switching power supply solution, the 1 SPOT Pro sets a new level of efficiency for power bricks, while still meeting the needs of musicians for low noise operation, even in severe conditions where the pedals themselves may generate interfering noise.

Can the 1 SPOT Pro power my pedal?
That question can best be answered by looking at the following questions and notes…
Which output and settings do I use for my pedals?
It is important for you to know the power requirements for your pedal. For every pedal that you are going to power via the 1 SPOT Pro CS6, you need to know the following:
What is the voltage required by the pedal?
Does the pedal require AC or DC voltage?
What is the polarity of the pedal? (Center pin positive or negative.)
These questions can usually be answered by:
- 1. Inspecting the pedal itself near the power jack.
- 2. Referring to the owner’s manual.
- 3. Checking online, or contacting the manufacturer
- 4. If your pedal can be powered by a 9Vdc battery, it can be powered by one of the 9Vdc outputs ( an exception being the Boss ACA pedals, see below).
Notes on using certain pedals with the 1 SPOT Pro CS6:
- Some older Boss pedals require 12Vdc, yet can be powered by a 9Vdc battery. They will indicate “Use ACA adaptor” near the power jack. To power an ACA pedal please use outputs 5-6, and set to 12Vdc on the DIP switch for the corresponding output. Modern Boss pedals will indicate “PSA,” and can be powered by any of the CS6’s 9Vdc outputs.
- Many germanium based fuzzes and Octavia-style pedals will require the use of the CYR adaptor to reverse the polarity to center pin positive.
- For pedals with high milliamp draws such as Strymon, please utilize outputs 1 or 2 that produce 500mA each.
- Eventide pedals such as the Time Factor and H9 may be powered by outputs 1 or 2 with the addition of the CL6 converter, for proper DC jack tip size and polarity.
- Line 6 M5 may be powered by outputs 1 or 2.
- Line 6 M9, and the modeling pedals (DL-4/MM-4), may be powered by outputs 1 or 2, and will also require the CL6 converter.
- Line 6 Tone Core pedals may be powered by any 9Vdc output.
- Line 6 POD or M13 cannot be powered by the 1 SPOT Pro CS6.
- If more 9Vdc pedals need to be powered, an MC5 daisy chain (sold separately) may be plugged into any of the 9Vdc outputs depending on mA draw. For adding one more pedal, use the included MC2 cable.
- Pedals that do not utilize a power jack, yet are powered normally by a 9Vdc battery, may utilize any 9Vdc output, along with the CBAT converter.
- TC Electronic Nova pedals may be powered by outputs 5-6 in the 12Vdc position.
- TC Electronic Classic and Tone Print series may be powered by any 9Vdc output.
- Digitech Whammy: Versions 1-4 cannot be powered by the 1 SPOT Pro CS6. Version 5 or Whammy DT may be powered by outputs 1 or 2.
- Radial Tonebone 15Vdc pedals can be powered by a 18Vdc output, using the Reverse Polarity Converter (CYR) included with the 1 SPOT Pro.
- Note: Outputs can each handle more than the stated mA number. However, it is important to never exceed the max. current rating of all outputs simultaneously.
