Product Description

Warm Audio WA73-EQ Microphone Preamp and EQ (WA73EQ)

Warm Audio WA73-EQ Microphone Preamp & EQ (WA73EQ)

The legendary 1073 wrote the book on characterful mic preamplification and EQ. These venerable circuits helped define the punchy sound of '70s rock — and countless recordings and live concerts ever since. Today, this coveted tone can be yours for a song, with the Warm Audio WA73-EQ mic/line/instrument preamp. In both design and performance, the WA73-EQ pays homage to the revered British console lineage that started it all. Throughout the audio industry, the 1073 is considered the holy grail of preamps and EQs, with a rich, sweet, and bold tonality that's ideal for making audacious statements with your music. After years of R&D, painstaking reverse-engineering, and countless hours of listening, Warm Audio captured the sonic essence of this classic perfectly in their boutique WA73-EQ. With 80dB of gain and a fully discrete transformer-balanced signal path, the sound is a revelation: harmonically rich bottom end, focused midrange, and slightly resonant highs.

Nice and Weighty But Wish the Top End was Smoother

I've had this mic pre for about three months. I'm liking it but I can't say I'm loving it. It definitely has some beef to it. I also heard some comparisons to Vintage Neve gear that proves it's very similar in that respect. But where it starts to roll of on quality is the smoothness of the top end. It's not a showstopper at all but isn't as smooth on the top as my Pacifica or LA610- which are transformer based mic preamps. So for vocals it's back to my Pacifica or LA610. This is best used on electric guitar and bass- at least in my world. If Warm could tighten up the smoothness of the top, it would be a 5-star mic pre. At the moment, I can't give it that.

Sounds good! Easy to dial in

I really like the sound of this 1073 clone. It has a deeper dimension of sound than what I can dial in after the fact using the plugin from Waves. The plugin is still quite useful but if I know I want this sound going in it is very worthwhile to use this hardware peice straight away. It is a really good addition to the other hardware channel strip I use (UA 6176). Between the two I can cover a wide range of sounds.


Modern and great sounding pre with plenty of i/o options. Gets plenty of use at the studio and out preformed pre"s costing twice as much. Nothing bad to say. Totally awesome!

Sam H.

I own preamps from Rupert Neve Design (modern Neve), Avedis Audio (transformer forward, 1073 style), API, UA and FMR Audio. I recently bought a pair of the WA73-EQ's. I actually bought two single space units vs. the two channel double space unit because I was concerned if I didn't like them, it would be easier to sell single units down the road. I AM BLOWN AWAY. I will be keeping these until I retire from audio. The EQ's alone are worth the price. The flexibility of the inputs on the face in addition to the back allow them to be wired in to my desk like all other pre's but access them easily when tracking bass or guitar in the control room. Every feature is well thought through. I can't say enough about them. These are a bargain and sound amazing.

Totally Legit

I bought 2 of these because the dual wa73 was out of stock last year. These things are legit, I've used the BAE 1073 for a few years and these deliver virtually the same quality at half the price.

If you have a home studio and have a typical home studio budget this has got to be the best preamp on the market that I know about.
