Pedal Power Draw Database: 325 Guitar Pedals Analyzed (Median 50 mA)

Key findings

• The typical pedal draws 50 mA. That is the median of 325 manufacturer-published current draws (mean 85 mA, pulled up by a few power-hungry units such as the 44 Magnum power amp pedal).
• 76% fit a standard 100 mA output. 246 of 325 pedals list 100 mA or less; 49 pedals (15%) sip 10 mA or less.
• Only 15 pedals (5%) list over 250 mA, led by the Electro-Harmonix 44 Magnum at 2000 mA and the EarthQuaker Devices ZEQD-Pre All-Analog Simulation Solution at 500 mA.
• Brand medians differ. Boss: 62.5 mA median across 58 pedals; EarthQuaker Devices: 25 mA median across 77 pedals; Electro-Harmonix: 55 mA median across 190 pedals.
• Strymon asks for a 300 mA supply most often. Strymon publishes a minimum supply rating rather than a measured draw; for the 17 Strymon pedals we checked it is 50–500 mA, and 8 of 17 specify 300 mA.
