1 SPOT Pro CS6 Low Profile Guitar Pedal Power Supply - Quiet, Isolated

Our review of the 1 SPOT Pro CS6 finds it ideal for gigging and home players who need a compact, flexible power source. The single biggest reason to buy is its combination of six fully isolated outputs and multiple voltage switch options, which lets a player power diverse pedals without noisy ground loops or bulky adapters. In practice the unit tucks under a pedalboard and delivers clean power, so this review will focus on real-world fit, noise performance, and how the switchable outputs handle pedals with different voltage needs.

Key Features

• Six isolated outlets: Each output is isolated to minimize noise and eliminate ground loop hum when running multiple pedals.
• Switchable voltage pairs: Two outputs toggle between 9V and 18V so boutique and octave pedals that need higher voltage can be used without extra supplies.
• Additional switchable outputs: Two outputs switch between 9V and 12V, covering pedals that require intermediate voltages without external converters.
• Two dedicated 9V outputs: The pair of fixed 9V outputs handle common pedals directly for straightforward pedalboard setups.
• Low-profile design: The compact, flat chassis is designed to fit under a Pedaltrain-style board and save space on stage or in a case.
• Included cables and adapters: The supply ships with the necessary cables so you can start wiring a board immediately without hunting for tips.

Who It's For

The 1 SPOT Pro CS6 suits working guitarists and hobbyists who run a mix of standard 9V pedals and a few that need 12V or 18V, and who want to reduce noise with isolated outputs. It is especially useful for players rebuilding a board who prefer a single brick under the board rather than multiple wall warts or separate converters.

Players who need extremely high current for many power-hungry digital pedals, or those who require uncommon voltages beyond 9V/12V/18V, should look for a supply with higher per-output amperage or additional voltage options. Studio engineers who require rack-mounted power may prefer a dedicated rack power system.

Pros & Cons

Pros

• Fully isolated outputs deliver very low noise, matching what customers describe as zero audible hum.
• Switchable 9V/12V and 9V/18V outputs add flexibility for boutique and octave pedals without extra gear.
• Compact, low-profile housing fits easily under common pedalboards and keeps the stage footprint small.
• Solid build quality and included cabling make it ready to install out of the box.

Cons

• Not intended as a rack solution; players needing many high-current outputs may need a larger supply.
• Limited to the voltages supplied; exotic voltages outside 9/12/18V require additional converters.

Frequently Asked Questions

Can this power supply power pedals that need 18V?
Yes, two of the outputs are switchable to 18V so pedals that require higher voltage can be powered directly from the unit.

Will it reduce hum in my rig?
Yes, the six fully isolated outputs are designed to minimize ground loop noise and customers report a near-silent setup when using this supply.

Does it include the cables needed to hook up pedals?
Yes, the unit ships with the necessary cables and adapters so you can wire a pedalboard without buying extra connectors.
