The Saturno Oxygen Buffer is an ultra-compact analog utility pedal from Brazil designed to maintain signal integrity in long effect chains. It converts high-impedance guitar signals to low-impedance, eliminating high-end roll-off and dynamic loss caused by extensive cable runs. The pedal’s standout feature is its versatility; it supports Mono, Stereo, Splitter, and Dual modes, with the latter allowing for simultaneous buffering at both the start and end of a pedalboard. It utilizes high-quality components to emulate the clarity of a guitar plugged directly into an amplifier with a short cable. The design focuses on maximum space efficiency and road-ready durability for professional rigs.
