In a brand new series of free Waves video tutorials, Eli Krantzberg will look at four of his favorite Waves compressor plugins and show you real-world examples of them in action. Featured in part one: the PuigChild 670.

Colorful Compressors

Logic Pro’s built-in compressor is fantastic. It’s got a variety of built-in models that emulate classic vintage style units. With its well thought out, detailed, and nuanced controls; it can handle just about any situation. Period.

So, why would you want to experiment and invest in third-party compressor plug-ins when Logic Pro X’s is so versatile?


For the same reason my wife enjoys having thirty-four pairs of shoes, while I am perfectly content with four. There’s no question that I kind find a tasteful accompaniment to every single item in my wardrobe with my modest but versatile shoe collection. My wife, on the other hand, can create an almost infinite set of variations in her ensembles with her collection of shoes in different colors, shapes, textures, and patterns. They contrast, compliment, and offset, the other pieces in her wardrobe in interesting and unusual ways.

And so there is the answer. Variety.


Logic Pro comes packed with excellent plug-ins. Variety is a luxury. Not only does it cost money to have a choice of additional plug-ins to select from, it also involves an investment in time to learn when to use them and how to get the most from them. Enter Waves. Not only do they model many classic hardware compressors extremely well; they also make them exceptionally easy to learn and to use musically. In this series of videos, I’ll look at four of my favorite of the Waves emulations and show you real world examples of them in action.

PuigChild 670

The PuigChild 670 is the Waves version of the classic Fairchild 670. The time constants on this model give it unique attack and release characteristics that make it useful for everything from very subtle “glue” like compression, to heavy pumping and breathing that can bring out the room ambiance in even the driest sounds. It works great either as an insert plug-in or is a send/return setup for parallel compression.

API 2500

The API 2500 has a really interesting variable knee control and high-pass filter (thrust) that tailors how transients and specific areas of the frequency range pass through the compression stage. Combined with its feed forward- and feedback style algorithms, it produces a broad range of musical sounding compression styles.

DBX 160

The DBX 160 has a unique envelope following attack and release algorithm that tracks transients in just the right way to get a super crisp and sharp sounding attack on percussive sounds. Blending in a subtle amount via its built-in mix knob allows for a unique punch, or smack, to be added to the initial attack; for a very percussive, almost rhythmic, style of compression.


Finally, the CLA 2A is modeled on an electro-luminescent optical attenuator called “T4” for gain reduction. Unlike tube and analog circuitry, it doesn’t add distortion when it modulates the sound. As a result, audio sounds greatly enhanced running through this plug-in, even when it is barely triggering any gain reduction. It’s program dependent multi-stage release algorithm makes it incredibly easy to use. No matter what you do with this plug-in, it sounds good!

So join me on this journey through the land of compressors, and decide for yourself how much of a worthwhile addition these might be to your collection of processing plug-ins. Personally, I opt to spend my money on plug-ins over shoes, while, given the choice, my wife would gladly make do with one versatile compressor. To each his own!

Explore the unique attack and release characteristics of this colorful compressor in both stereo and mid/side mode. Hear how it can produce everything from subtle warm sonic “glue”, to sharp pumping and breathing transients that bring out the space and room sound in the underlying track.

The Waves PuigChild Compressor, modeled on a vintage Fairchild 670 housed in Jack Joseph Puig’s own studio, is currently on sale for $129 (regular $349).
