Truetone 1 Spot Pro CS7
The Truetone 1 Spot Pro CS7 is a professional-grade multi-output power supply designed to provide clean, isolated power to a variety of guitar effect pedals. Developed over a three-year period, it utilises switching power technology and a robust steel enclosure to cater to the requirements of touring musicians.

Background and Development
The 1 Spot Pro CS7 is the result of three years of experimentation and technical development by Truetone. The brand's goal was to evolve their original 1 Spot technology into a comprehensive, multi-output unit capable of handling the complex power requirements of modern pedalboards. This development phase focused specifically on eliminating common noise issues associated with powering multiple effects simultaneously.
Key Features and Technical Design
The CS7 is distinguished by its use of switching power technology, which allows the unit to operate efficiently across different global voltages. The device features seven isolated outputs, offering a mix of 9V, 12V, and 18V DC power options. This versatility ensures compatibility with standard pedals, such as the Boss DD-3T Digital Delay, as well as high-voltage requirements found in boutique units.
To ensure durability for the 'gigging musician', the internal electronics are housed in a heavy-duty steel chassis. This design choice is intended to withstand the rigours of the road and frequent transport in pedalboard cases.

Sound Character and Performance
The primary performance characteristic of the CS7 is its focus on 'clean, noise-free power'. By isolating the outputs, the unit prevents ground loops and electrical interference that often plague daisy-chain setups. This is particularly critical when using high-gain effects like the Electro Harmonix Big Muff Distortion or noise-sensitive utility pedals like the Boss NS-2 Noise Suppressor.
Compatibility and Alternatives
The CS7 is designed to be a universal solution, capable of powering everything from simple analogue units like the Fender Hammertone Flanger to digital pitch-shifters like the Digitech Whammy Ricochet.
While players using smaller boards might consider single-output adapters, the CS7 competes with other multi-output units by offering a balance of 9V, 12V, and 18V outputs in a single chassis. For those requiring even more outputs, larger versions in the 1 Spot Pro series are available, though the CS7 remains a standard for medium-sized boards.
