The RAD Custom Shop Blue Channel is a boutique overdrive pedal handcrafted in Brazil, inspired by the classic Marshall Bluesbreaker circuit. It is designed to deliver a transparent "low-to-medium gain" drive that preserves the natural dynamics and frequency response of the guitar and amplifier. Unlike the original vintage units, the Blue Channel features modern modifications including an increased output volume and a more refined tone control for better clarity. The simple three-knob interface—Level, Gain, and Tone—allows players to dial in everything from a subtle clean boost to a rich, harmonically detailed crunch. Its responsive gain structure makes it particularly effective as an "always-on" pedal for adding tube-like warmth to a solid-state or clean tube rig.
