$149.00 $99.00


Paying homage to the classic American two-stage circuit originally manufactured in the 1930's through the 1950's, the CA-70S perfectly encapsulates the huge thick tone that is what many consider to be the quintessential “old tube preamp” sound. Utilizing our component level modeling technology and meticulous refinements with the team at Coil Audio, we were able to bring the sought after sound of old octal tube circuits into the modern world.

Introducing, MixWave: CA-70S

Dripping with color

The CA-70S is extremely easy to use and immediately transforms any signal with its warm sounding octal tube circuit. The Input section includes Mic and Line amp models that go from subtle dynamic saturation to blown out distortion, a phase reverse switch, and a 4 position pad network.

The perfect pair

The Low and Negative Feedback controls perfectly interact with each other to sculpt, color and change the depth of the signal. The Low switch moves the low end from front to back while the Negative Feedback control ranges from a bright, forward sound with raised harmonics to a darker tone with a smooth and dampened harmonic structure.

Built for modern workflows

Exclusive plugin only features enables modern workflows to this classic preamp. Get instant parallel processing with Dry/Wet mix controls, use the input and output filters to high-pass or low-pass before and after the signal while working beautifully on mono or stereo signals; bringing the iconic Coil Audio sound to a new age.

There are a lot of mojo box plugins on the market, yet the CA-70S has a different flavor than the others. Massive bottom and some nice dial-able warmth really sets it apart from the crowd. It's a great plug to add some spice to your mix or master!

The CA-70s gracefully enhances every source it's applied to, imparting a delightful warmth that effortlessly eliminates harshness. This plugin has a magical touch, transforming even the most brittle digital elements into a rich and lush auditory experience with unparalleled simplicity.

Using the CA-70S has made even the cheapest string and pad VSTs feel real and warm.


Mix Engineer (Chris Brown, Offset, Jack Harlow, Coi Leray)

The CA-70S allows me to bring life back into tracks when I am only given the 2 track beat to mix. Often times when people lose the beat files, we are forced to mix with the MP3. I now feel much more confident in these mixes because I can get the low end and fidelity back into the 2 track with the CA-70S.

Benjamin F. Thomas

Mix Engineer (Lil Uzi Vert, Future, Travis Scott, Jazmine Sullivan, Nicki Minaj, Fridayy)

The CA-70S is truly a magic bullet because it just makes everything sound better. It gives you that 3D front to back depth reminiscent of the analog days but without the limitations. 

Damien Lewis

Mix Engineer (Justin Timberlake, Lizzo, Rihanna)

From clean and round sounding to crunchy and burnt - the CA-70S does it all in a really elegant way. It's been finding its way in a lot of tracks in my mixes.

Ryan Schwabe

Mix & Mastering Engineer (Baauer, BAYNK, Fridayy, Tobi Lou, Ellie Goulding)

The CA-70S is perfect for adding texture, weight and depth to any source and the controls are spot on. Simple and powerful.

E. Dan

Producer & Mixing Engineer (Wiz Khalifa, Mac Miller, Juicy J, Earthgang, J.I.D.)

The CA-70s does what 5 other plugins were doing in my master chain and it does it way better. Reminds me of my analog summing days.

Nacho Molino

Mix Engineer (Ruben Blades, Carlos Vives, Omara Portuondo, Natalia Lafourcade, Joan Manuel Serrat, Diego Torres)

The CA-70S sounds like adding a warm hug to any instrument.
