All-Analog Tools

Mastering is a specialization within the world of audio. It's all we do, and we do it right.

After more than 20 years in business — and over 1,000 projects under our belt — we realize there's no substitute for experience, attention to detail, and professional integrity. The best equipment doesn't hurt either.


Our custom all-analog mastering console provides the perfect finishing touch to your recordings, revealing clarity, impact, power, and detail that you never thought possible in your digital mixes.

Hand-selected pieces from Dangerous Music, Maselec, AnaMod, and Pendulum. Monitored though the Lynx Hilo AD/DA, controlling Lipinski L-707 speakers (bi-amplified by Lipinski monoblock amps) and B&W subwoofers. All work spot-checked with Audeze headphones. Everything is connected with DH Labs SilverSonic cable and powered by the Sowden Softbrew system (a nod to Doug Sax's famous coffee comment...).

Need digital processing? We work "in the box" when needed and have best-in-class digital tools for those occasions, as well as the best software for audio restoration if a bit of clean-up is required prior to mastering.

Behind The Gear

Behind The Gear

ZenMastering is San Diego's longest-running dedicated audio mastering studio, founded in 2000. We're owned and operated by renowned mastering engineer Paul Abbott.


Paul has been featured in Music Connection's "Masters of Mastering" series and appeared as an expert columnist for many of pro audio's leading publications. One of Paul's articles was even cited in Damon Krukowski's acclaimed book The New Analog.

Paul's perspective on mastering comes from decades of playing music, making recordings, critical listening, and rigorous comparative audio/sonic analysis. Paul's mastering philosophy is that the highest-quality, properly matched analog gear produces the best results.

Frequently Asked Questions


Q: "Are your mastering prices negotiable?"

A: We’ll happily discuss your budget and your project. Our goal is to make your recording sound its best.


Q: "Why wouldn't I just use a less expensive, automated mastering service like LANDR, Cloudbounce, eMastered, or Masterchannel?"

A: Sound quality. Automated/AI digital plug-in mastering can't compare with all-analog mastering done by an experienced professional. Check out this article from Music Radar comparing four automated/online mastering services to a professional mastering engineer. The takeaway quote is, "...on balance, it is reasonable to expect an experienced mastering engineer to beat an AI on every metric...".
