Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Truetone One Spot 9V.

Use cases and applications

  • Ideal for small pedalboards; effective for home use and easy pedal swapping.

    Source
  • Some users successfully power up to 10 pedals with the CS6 by giving digital pedals their own outputs and daisy-chaining analog pedals.

    Source

User experience

  • Long-term users report reliability, though some experience noise and premature failure after a year.

    Source
  • Owners appreciate the color-coded cables for easy organization, but advise against using the red cable unless absolutely necessary for specific AC pedals.

    Source

Setup and maintenance

  • Works well with under 800mA total pedal draw; noise can be mitigated by separate power for high-draw pedals.

    Source
  • It's crucial to avoid using the red-bordered outputs unless a pedal specifically requires 18V or AC current, as misuse could damage pedals.

    Source
  • When powering the HX Stomp, it can be connected to a 500mA socket using a green Line 6 plug, a reverse polarity plug, and a standard plug.

    Source
  • To prevent accidental use, some owners cover the 9V AC jack with gaffer's tape, as using it incorrectly could damage pedals that don't require AC power.

    Source

Comparisons

  • Some owners transition to isolated power supplies like the Strymon or IsoBrick for reduced noise and performance reliability.

    Source
  • Multiple 1Spot units can be a budget-friendly alternative to the CS6, especially for setups with many digital pedals, due to the lower noise when under 200mA.

    Source

Value and pricing

  • Considered a budget-friendly option; used units typically sell around $30, offering good value despite noise issues.

    Source

Features and functionality

  • The CS6 allows for powering more than its 6 outputs by daisy-chaining, with one owner using a single 500mA output for multiple analog pedals.

    Source
  • For tone experimentation, the Big Muff pedal benefits from voltage sag, achieved by adjusting the dial to 5V-7V, mimicking the effect of a dying 9V battery.

Almost Magic

For a single, cheap power source, this manages to power my pedalboard using daisy chains alone with minimal interference. I plan to use this until my board gets complicated enough to upgrade, but it's really the only option needed more a starter/basic board.

Solid starter choice

When buying your first pedal, this is a solid choice to power it. Otherwise, there are better options, and using this with a daisy chain can cause damages and/or unwanted noise on bigger pedalboards

"I re-arrange my board before each tour, depending on what set we’re playing... Powered by a Decibel Eleven Hot Rod Deluxe and a few One Spots. I use each of these pedals through out our set, but the main ones in use are definitely my delays, reverbs, and the Whammy."
