Everyone needs a clean boost in their signal chain! Ideally suited for both guitar and bass. Mr. Boost is a transparent workhorse designed with a boot-strapped power supply that delivers 27dB of boost and up to 12Vpp of clean output signal from a regular 9V supply.

Greenchild gear is designed with premium, audio-grade components and meticulous attention to detail. Our pedals will serve as valuable tools in your tone arsenal for many years to come!
