You ever have an itch you can’t scratch? Well, it has been like that keeping my mouth shut about the Power Rox PRX150-Pro. Ever since I played with the early prototypes, I’ve been completely blown away by this attenuator! This is a totally new take on attenuator technology, folks, and I’m hoping it takes the industry by storm. Why? Simply because what we’re talking about with the Power Rox is true transparency in tone when this is in your signal chain; not “almost” transparent, but truly transparent.
Most comparisons between attenuators revolve around what’s the “most transparent” attenuator, indicating that really none of them are transparent, so people pick the best of the lot. And frankly, I’ve tested out several attenuators and ended up with the Dr. Z Airbrake, as I felt it was the most transparent out of the ones I tested. But nothing could have prepared me for the transparency of the Power Rox.
I could go on and on, but I won’t. In fact, I had already written a significant amount of text, but decided to just point you in the right direction. Go to the product page. Read through the product description, but more importantly, read the supplementary documentation behind the links at the bottom of the page. Jeff Aragaki has graciously provided some very in-depth articles on how attenuators work, and also provides a high-level explanation of the technology behind the PRX150-Pro.
Other manufacturers may brag about the safety and transparency of their attenuators, but none is willing to back up their claims with the engineering behind their attenuators (and if you knew what some were doing, believe me, if you care about your tone and the safety of your amp, you’d get worried). If you’re interested in or even use an attenuator, you owe it to yourself – and your tone – to check this unit out!
