■ EQ-1A
EQ-1A is a processor that emulates a vintage EQ that is considered the classic passive EQ. It uses a
distinctive style of operation, with controllable boost and attenuation (cut) for each of two regions,
low and high. The frequency response is completely different from that of a typical EQ, giving this
model its unique character. The input/output circuit and vacuum tubes also give the sound an
extremely musical character, producing a well-balanced sound.
