The T-RackS EQ 73 from IK Multimedia is a plug-in module based on part of a classic, large-format British mixing console, and features a preamp section and 3-band EQ. The original hardware was first introduced as a standalone rackmount module in 1970, and quickly became a studio staple, favored by recording engineers the world over for its rich harmonics and full Class-A sound.
All of the gain stages, circuit designs, and EQ curves and shapes been extensively modeled in the software, including the preamp behavior, saturation, and preamp/EQ interaction. The tone-shaping capabilities don't stop with the analog-sounding EQ, since the preamp section is able to add "grit" or distortion to tracks, resulting in a wider sonic palette.
The 3-band EQ can be used to add character to even the most "sterile" or cold tracks. High-end air and low-end punch can be boosted without ever sounding harsh or boomy, while the "presence" band is an invaluable tool for sculpting the body of a track. The plug-in can sound great on virtually every audio source, but especially kicks, snares, overheads, bass, guitars and vocals.
