Guitar Pedal Power Supplies

About

The Foundation of Silent Tone: Why Isolated Power is Crucial Many guitarists spend thousands of pounds on premium guitars, amplifiers, and boutique pedals, only to power them with a cheap, non-isolated daisy chain. This is the primary cause of ground loop hum, high-frequency digital whine, and inconsistent pedal performance. A true isolated power supply features independent transformers (or custom-shielded switching networks) for every single output. This completely isolates each pedal's electrical ground, eliminating ground loops and keeping your signal path whisper-quiet. Furthermore, modern digital pedals (like Strymon, Eventide, and Line 6) have high current draw requirements, often needing 300mA to 500mA of current. Under-powering these units can cause them to glitch, reboot, or sound thin. A professional power supply allows you to manage both current draw and varying voltage requirements (such as 9V, 12V, or 18V) safely and efficiently. 🔧 Rigorous Inspection Every power supply is thoroughly tested, voltage-verified, and safety-checked by our in-house technicians before being listed for sale. 🛡️ 12-Month Warranty We stand behind every product we sell.

Advanced Features: Voltage Sag & High-Current Outputs Some premium power supplies feature a voltage sag control on select outputs. This allows you to manually sweep the voltage down from 9V to around 4V, emulating the sound and feel of a dying carbon-zinc battery. This is highly prized by tone purists for vintage fuzz and overdrive pedals, introducing a unique, warm compression and "spitty" texture that is impossible to replicate with stable power.
