The sound of countless hit records

Those of us at Sweetwater who have worked on vintage Neve boards can tell you: if you've got good-sounding, well-miked sources, just push up the faders and you're in great shape. Kick in a 1073 equalizer and all bets are off: this is the best-sounding EQ you've ever heard. That's what you get with the Heritage Audio 73EQ JR. Massive, punchy, vibrant sound that seems to leap from your speakers. It's the sound that created countless hit albums, and you've got it on tap with the 73EQ JR 500 Series module.

All the EQ you should ever need

The original 1073 was designed in 1970 as purpose-built preamp/EQ module for Neve 80 Series consoles. Like the original, the Heritage Audio 73EQ's high and low bands are shelving Baxandall types; the mids are fixed-Q dual-inductor based. It's broad-strokes EQ, but it sounds incredible and it's all you may ever need. As a side note: if you have tracks that require surgical EQ precision, chances are good you're doing something wrong earlier in the signal chain.
