This 1972 dual‑channel mic, line and instrument preamplifier puts two identical channels of what appear to be the same preamp design as in the 1977 into a 2U 19‑inch rackmount case.
These plug‑ins are all about warmth and distortion, and the flavours on offer range from gentle saturation at the subtler end of the scale through to crunching overload and squelchy obliteration.
