The Maxon SB-300 Master Switch in the wide-box format is a vintage utility pedal from the late 1970s to early 1980s, making it a rare and collectible piece of gear. Designed as a master bypass switcher, it allowed guitarists and bassists to control entire pedal chains or signal paths with a single stomp, a forward-thinking solution well before modern loop switchers became widely available.
This wide-box version offers a slightly different enclosure style compared to the narrow-box variant, while still maintaining Maxon’s rugged build quality. Featuring a sturdy metal chassis, a single heavy-duty footswitch, and durable input/output jacks, the SB-300 was built to withstand stage use and provide simple yet effective routing control.
Today, the wide-box SB-300 is highly sought after by collectors and vintage pedal enthusiasts due to its rarity and its place in Maxon’s early pedal history. Whether used as a practical tool for vintage-inspired rigs or as a collector’s piece, it represents an important chapter in the evolution of effects switching.
