With three-stage amplification, moderate drive, hard knee, fast attack and medium release, the BA-6A delivers Vari-Mu style valve compression, or as it’s often called – true tube compression. Unlike later opto valve compressors, Vari-Mu designs can offer faster attack, variable release times and more musical, forgiving compression.
Due to the nature of its circuitry, the BA-6A is known for its high gain and full, yet gritty sound. This unit earned its reputation for being abused by Jimmy Page and is responsible for much of his huge-sounding guitar recordings.
