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.”

Features

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 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.


Multiple Voltages

18vdc-12vdc variable
While most pedals still run off 9VDC, not all of them do. That’s one of the main reasons why we finally decided to design the 1 SPOT Pro. With the CS7, you get one output for 18VDC and six at 9VDC, with four of those switchable to 12VDC. Need another 18VDC output? No problem… just get a Multi-Plug 2 cable (MC2) and run both pedals off that one outlet… most boosts and drive pedals don’t mind sharing an output anyway. Don’t need the 18VDC output at all? No problem… just get Truetone’s 18V to 9V Converter cable (V189).

With the CS12, you get the same voltage options that the CS7 has, plus a variable 4-9VDC output, and the 9VAC output.

Worldwide input voltage

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 CS7, don’t care what the input voltage is.cs12-back-all

Rugged Steel housing

vent-end-altIf you’re a touring musician, or even if you just play at the local pub regularly, you know how important it is to have roadworthy 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.

Pure Isolation

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.


Pedaltrain Mounting Brackets

mounting-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!


Energy Efficient

energy-effPrior 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 CS7, 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 (exception being the Boss ACA pedals, see below).

 

Notes on using certain pedals with the 1 SPOT Pro CS7:

 

  • 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 2-5, 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 1 SPOT Pro CS7’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 6 or 7 that produce 500mA each.
  • Eventide pedals such as the Time Factor and H9 may be powered by outputs 6 or 7 with the addition of the CL6 converter, for proper dc jack tip size and polarity.
  • Line 6 M5 may be powered by outputs 6 or 7.
  • Line 6 M9, and the modeling pedals (DL-4/MM-4), may be powered by outputs 6 or 7, 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 CS7.
  • If more 9Vdc pedals need to be powered, a MC5 daisy chain (sold separately) may be plugged into any of the 9Vdc outputs depending on mA draw.
  • 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 2-5 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 CS7. Version 5 or Whammy DT may be powered by outputs 6 or 7.
  • 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.

 

  • If you have a pedal that cannot be powered by any output on the 1 SPOT Pro, get our Courtesy Plug Cable and plug your adapter into that.

1 SPOT Pro Testimonials

"It's funny just how quietly the 1 SPOT Pro operates. I built my home tracking/recording pedal board recently, and when I went to plug it in, I was sure that I must have had a bad cable or something, as none of the usual background noise was present. No white noise from the drives, no throb from my tremolo pedal, and no wah noise when engaged. I grabbed my guitar, plugged in, and everything worked flawlessly. It was so much quieter than my past power supply, that when I didn't hear the background noise I was used to, I thought something was wrong. Nothing was wrong at all, it was just that much quieter. In fact, it was dead quiet. This is the best testament I can give for a power supply."

-Tyler Chiarelli
Guitarist/Band Leader - Florida Georgia Line

"The 1 SPOT Pro is absolutely phenomenal!  What a brilliant design."

- Jim Messina

 

"PSA for all the guitar nerds out there... I recently switched to this new power supply by Truetone effects for my home studio rig. It solved SO many noisy, power gremlins... Unreal. Power is a constant battle for us. Single coil noise and light switches and ground hum and all... Whatever this thing does, it HELPS. Plus it powers all the big stuff too. (M9, Strymon, Memory Man, etc...) Pretty knocked out by it..."

-Derek Wells, 2016 ACM Guitarist of the Year
