SKU: # 490375
Model: #



The WA-412 provides 4 channels of classic American console preamps in a sleek 1RU design. This style of preamp is often referred to as "the sound of Rock n' Roll" for its BIG punchy low end and smooth open top end. Featuring fully discrete socketed 6-pin opamps and custom wound Altran USA input and output transformers, the WA-412 leaves nothing to be desired. If you are looking for multiple channels of world class tone in an affordable package, the WA-412 is the right choice for you.

The WA-412 has all of the features one would expect from this style of preamp... and more. Output Trim has been added to every channel for precise control and creative gain structuring. We also added a Tone switch (transformer input impedance) to each channel, which allows you to choose the warm and punchy classic console tone, or a more open & neutral sound.

Carefully choosen components has resulted in an amazing four channel 'workhorse' preamp/DI that performs at the highest levels, while still adding a touch of vintage console magic to your signal.

I have only tracked for a day with this pre, but my snare and toms are sitting nice with the gain up 2/3 and the output around 1/3. Getting some deep tones with pre and the low end is disgusting! Wish they made an eight channel version. Quality is SOLID, hand made. No questions, this pre, like their other gear is beyond reproach and is more than merely a 312 copy, but will likely hold a place in most drum rooms' racks for years to come. Plus, if I ever get bored of the sound, I can drop in any 2520 opamp for experimentation. Pretty slick!
