a brand called Golden Age Project EQ81.It's designed to distort and ad noise to simulate older recordings played through older tubed equipment.
@jtcf That's called an EQ81 because they are emulating the sound (and circuitry) of the classic Neve 1081 4-band eq. This is a 70's era Neve console EQ designed for mixing and tone shaping. This EQ has color & personality, and is really meant for mixing. It's not super transparent and does not emulate a tube eq. It's solid-state all the way. I've got a Great River EQ-2NV which is also a "Neve-alike" eq. It sounds amazing for shaping individual instruments and buses. The high & low shelfs do make good bass & treble controls for a stereo mix. The mid bands have a bit of color, but are a bit narrow for a stereo mix. Look up the original Neve 1081... it's beautiful! I've used Neve preamps, but not the 1081.
