History of the Acoustic 360

• Introduction (1967): The Acoustic 360 was introduced by the Acoustic Control Corporation, founded by Steve Marks and his father Robert in Van Nuys, California. Designed by Russ Allee, it was a groundbreaking bass amplifier that combined a solid-state preamp (Model 360) with a powered speaker cabinet (Model 361). The cabinet featured an 18-inch Cerwin-Vega speaker in a folded horn enclosure with a built-in 200-watt power amp, delivering exceptional volume and clarity.
• Innovative Features: The Acoustic 360 introduced several unique features for its time:
  • Variamp Tone Control: A rotary EQ selector allowing precise frequency adjustments.
  • Built-in Fuzz Circuit: Adding distortion for aggressive tones.
  • Electronic Tuning Fork: A novel feature to aid in tuning.These features made the amp highly versatile and capable of handling a wide range of musical styles.
• Tonal Characteristics: The Acoustic 360 was celebrated for its deep, punchy low end and clear mids, making it ideal for both live performances and studio recordings. Its folded horn design projected sound powerfully over large distances, making it a favorite for outdoor festivals and large venues.
• Legacy: The Acoustic 360 became synonymous with the sound of bass in the late 1960s and early 1970s. It was widely used by influential bassists of the era and remains revered as a vintage classic. In 2011, Acoustic USA reintroduced a modern version of the 360/361, ensuring its legacy continues into the present day.
