Critic Reviews

“All of the Eric Johnson signature sounds are inside this preamp and power amp”: Vertex Effects played Eric Johnson’s $400,000 Dumble rig – here’s what it sounds like | Guitar World

guitarworld.com

The Dumble Manzamp Preamp, featured in Vertex Effects' video, unveils a rare gem from the Dumble line. While the preamp and Odyssey power amp combination is heralded for capturing the essence of Eric Johnson's signature tones, the hefty $400,000 price tag may deter many potential buyers. The preamp excels in delivering stunning crystal-clear cleans and powerful overdrives, even when paired with effects like a Fuzz Face and a Tube Screamer. However, its exclusivity and the notion that "most Dumbles are not known to take pedals particularly well" might limit its appeal to only the most die-hard collectors and enthusiasts.
