Designed by Manuel Jano Acevedo and Daniel Schwartz, this pedalboard-sized powerhouse caters to both the worship musician and the rock enthusiast, with dual independent signal paths that allow you to craft clean and dirty channels or run contrasting tones in parallel.

Critic Reviews

The Big Review: DSM & Humboldt Simplifier DLX

guitar.com

The DSM & Humboldt Simplifier DLX showcases a rich array of features, offering an impressive analog amp and cab simulation experience with built-in stereo reverb that elevates its versatility for live and studio use. Its two-channel setup allows seamless clean and dirty switching, and the tonal variety—especially in British-style crunch—is commendable. However, the overwhelming number of controls can be daunting, making it less "simple" than its name suggests. While the sound quality impresses, especially with Vox and Marshall emulations, the lack of certain output stage emulations can be a letdown for purists. Overall, it's a solid choice for those willing to navigate its complexity for a rewarding tonal palette.
