daisy chain

A daisy chain is a group of power supply plugs linked together so several pedals can be powered from one single power supply¹. It works as long as the total current draw in milliamps does not exceed the supply's limit, no matter how many pedals are connected¹. Daisy chaining analog pedals such as compressors, overdrives, and distortions generally works, while digital pedals such as reverbs, delays, and modelers generally want their own isolated output². Ground loops in a daisy chain can allow stray magnetic fields to introduce hum into the signal path, and modulation and delay pedals make such problems likely³. Pedals with positive ground circuits may need a voltage inverter to work in a daisy chain with negative ground pedals⁴.
