Warm AudioWA-412 4 Channel Microphone Preamp and Instrument DI, Black

Killer pres. Big defined low end. Clear mid range when tone button is disabled. Tone button definitely adds a mid range boost, but you have to be careful not to overdrive it, top end is musical. What more can you ask for for this price? Volume knobs are ok, but that’s not a deal breaker for what you get here. 5 stars

Very competitive with the api 3124+Knobs are fun too!

I've owned this preamp for about a year now and used it pretty extensively in my studio to record everything from garage rock to Appalachian old-tyme. It's an amazing piece of gear not only because of the value but because it really sounds fantastic on a number of instruments. The WA412 is meant to "clone" the API sound, which is punchy and has a bit less "color" than something like a Neve. The WA412 does this nicely... it's not exactly an API but its similar, and has a lot of nice characteristics that set it apart from other preamps, (including the WA12 single channel, which I also own). Most notable, in my opinion, is it's amazing bottom end. This thing is punchy as heck, and captures drum kits with a detail and body that makes mixing a breeze- the first time I tracked drums with it I was kind of flabbergasted and I just sat there for a minute listening to the playback wondering if I'd accidentally engaged some EQ plugin or something, but no... the 412 just sounds that good.The WA412 also excels at tracking acoustic / electric guitars and bass (the DI input works great for this), and produces killer vocals when paired with an SM7b especially. It also has plenty of gain for ribbon mics. There's really not much you CAN'T do with this from a tracking perspective, though I tend to prefer it on drums the most.I do wish that it had line-level inputs to allow the preamps to be bypassed so that it could more easily be used on a 2bus during mixing... I have a small studio with limited control room space, so I prefer gear that can be utilized for multiple tasks. However, the WA412 is first and foremost a preamp, not a mixing tool, so it's not a big deal. My only other complaint is that the knobs and buttons are pretty small and thus are a little finicky for those of us with big hands. But they smashed 4 channels into one single rack unit so there's obviously not a lot of extra space!For 1000 bucks you get 4 channels of API-ish goodness, and that's a steal of a deal- especially seeing as how it sounds amazing and comes from a company that seems to care about providing affordable, quality gear to those of us who can't just go out and buy vintage high end gear. I've talked with Bryce on the phone about Warm's products and he's a really nice dude who was happy to answer all my questions. Great company, great product.

Perfecto, muy buen servicio y producto

used it for my recording (snare and kick) last weekend, gave me an excellent result...much better pre-amps than the ones on my interface. Next weekend, attacking vocals with it!!!
