A brick pedal, often referred to as a “brick” power supply, is a robust, compact, and reliable power source designed to provide consistent power to multiple guitar pedals. These power supplies are essential for musicians who use several pedals in their setup, as they ensure that each pedal receives the necessary voltage without risk of interference or power instability.

The name “brick” comes from the shape and size, which is typically large and boxy, much like a brick. These power supplies often feature multiple isolated outputs, preventing hum and noise from leaking between pedals, and can supply various voltages (such as 9V, 12V, or 18V) to accommodate different pedal requirements. Popular brands like Voodoo Lab and Truetone make high-quality brick power supplies that are built to withstand the rigours of live performances and provide reliable performance.
