"What's great about the Workhorse — especially for guitar players who are serious about home recording — isn't just the typical Radial quality and innovation (although that's definitely a bonus), but the fact that the unit offers so many guitar-oriented applications."

"It's hard to imagine squeezing any more functionality into a 3U device like this, and Radial is to be congratulated for putting plenty of thought and design smarts into such a compact and attractive package."

"The Workhorse is a more sophisticated, more capable, and more costly re-thinking of what a 500-series rack frame should be."

"When Radial announced that it was working on a 500-Series it generated much interest... the Workhorse will be an excellent addition to any studio and is the perfect choice for bringing analogue processing to a DAW-based studio."

"The Workhorse is a huge step forward in the 500-Series world, and from its build quality to its feature set and its open-ended architecture, it is currently unrivaled for supremacy."

"We don't like to nag, but if you're into the 500-series form factor, you must check this out... If you've got a few 500 series modules out in the back paddock or are thinking of buying into the format, the Workhorse definitely wont leave you with a long face. Now where did I put my saddle."

"Radial Engineering seems to like solving pro audio problems... So when I heard that Radial was building a 500-series rack, I was curious, because I assumed this rack would be overbuilt, well though out and versatile. I was right. The damn think looks like you could drop it off a truck and it would survive, but there's a lot more to it than that."

"The Radial Engineering Workhorse certainly lives up to its name. It is a versatile tool for live and studio use. I found it easy to get excited about using 500 Series modules with the Workhorse... a great unit and reasonably priced for what it offers. The feature set is deep, the system is scalable, construction is solid and it sounds great. What's not to like?"

"The Radial Workhorse is one of the most versatile and well-equipped racks I've ever tried, and exudes the typical Radial Engineering detail and thoughtfulness... if you are thinking of embarking down the 500-series road, the Workhorse rack has to feature very highly on the list of contenders."

"Despite having a comparable boatload of features, operating the Workhorse is designed to be simple and intuitive... I ultimately tried every connection and function the Workhorse offered and found it all worked as promised…the big question is whether this Radial mixer is worth its premium price. I believe it is. It is truly professional grade and worth the cost for its applications in location recording, DAW output summing, tracking with parallel compression and other flexibilities."

"Radial is expert at eliminating hum and noise from guitar signals, and in the Workhorse that knowledge has been put to good use... The Workhorse certainly makes a terrific host for modules – sturdily built with useful routing features and extensive connectivity... Whichever 500 Series modules you use the Workhorse makes a great home for them."
