Legendary artists like Brian Eno, Stevie Ray Vaughan, and Peter Gabriel have made the chorus effect an essential part of music history since the 1980s. The 3RD DIMENSION BBD-320 brings this iconic sound within reach as an incredibly affordable analog multi-dimensional signal processor that captures those classic tones heard on countless legendary recordings.
Built around authentic Bucket Brigade Device (BBD) technology, the BBD-320 maintains the quality and character of original 80s circuitry while providing rich chorus sounds that enhance guitar, synth, and bass tones. The unit features a pure analog signal path that preserves signal integrity throughout the processing chain.
Operation couldn’t be more straightforward with the BBD-320’s four-button design – no complex speed, tone, or depth controls to navigate. Button 1 provides subtle warble effects, while button 4 creates more intense chorus sounds. You can press two buttons simultaneously to stack choruses for more nuanced effects, and remote switching is possible via the front-mounted ¼” footswitch input. A precise 10-segment LED meter allows easy monitoring of output levels.
