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.”
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 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.
We recognize that not all guitar pedals run off 9V. That’s why all 1 SPOT Pro models have outputs that can put out 9Vdc, 12Vdc or 18Vdc. The CS12 even has a variable voltage output for old-style fuzz pedals, and a 9Vac output for certain Line6 and Digitech pedals. And if you need to change the voltage of an output, Truetone also makes inexpensive converter cables to help you. There’s theVoltage Doubler, which does exactly what its name says, and the18V to 9V Converter... which also does what its name says. They don’t have the most clever names, but they get the job done!
Just like with the original 1 SPOT, and your laptop power supply and phone charger, the 1 SPOT Pro uses switching power supply technology which allows you to use it anywhere in the world. The CS12 has an input voltage switch on the back, which switches voltage only for the 9VAC output, since that output does use a toroidal transformer. The rest of the outputs on the CS12, and all of them on the CS6 and CS7, don’t care what the input voltage is.

The only power brick to include easy-to-install mounting brackets for Pedaltrain pedalboards. We even duplicated the output labels under the unit, so you can easily see which output is which, when working on your board. Yes, we thought of that too!
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.
