Description

Unlock the limitless potential of your guitar tone with the DSM & Humboldt Electronics Simplifier DLX, an innovative zero-watt, dual-channel stereo amplifier that perfectly bridges classic sound with modern technology. Designed for musicians who crave boutique sound possibilities and portability, this amp and cabinet simulator offers an all-analog experience, enriched with multi-stage reverb and ultimate connectivity options, all within an incredibly compact design.

The Simplifier DLX features two fully independent studio-grade preamps capable of modeling iconic amplifier tones, giving you access to three preamp types (MS Brit, American, AC Brit) and three gain modes (Clean, Crunch, Lead) per channel. Channel A is optimized for aggressive and expressive playing, while Channel B delivers a warmer, rounder sound perfect for clean tones and blues crunch to heavy rock rhythms.

Its ultra-connectivity platform provides flexible use as a stereo 2-channel amplifier, two-parallel amplifiers, or for dual guitar use, each with its own amp and effects loop. With stereo FX send and return jacks, DI outputs, and 1/4-inch outputs, you can effortlessly integrate the Simplifier DLX into any setup, whether recording, performing, or practicing silently with its high-grade headphone amp.

The Simplifier DLX’s multi-stage stereo reverb enhances your soundscapes with three distinct modes: Room, Plate, and Ether, allowing independent mix control for each channel. Crafted with a robust aluminum chassis, this pedal is built to withstand the rigors of both studio and stage environments.

Critic Reviews

The Big Review: DSM & Humboldt Simplifier DLX

guitar.com

The DSM & Humboldt Simplifier DLX packs a wealth of features into its compact design, offering impressive analogue amp simulations and flexible routing options. Despite its daunting array of controls, it achieves a solid British crunch and a surprisingly vibrant Vox tone. The built-in digital reverb enhances versatility, though the absence of a spring reverb option is a notable oversight. Users might find the learning curve steep due to its complexity, and some controls could be difficult to read in certain lighting. Nevertheless, for those willing to navigate its intricacies, the Simplifier DLX promises a rewarding sonic experience that rivals larger setups.

DSM & Humboldt Simplifier DLX Review - Premier Guitar

premierguitar.com

The DSM & Humboldt Electronics Simplifier DLX is a formidable pedalboard amp that packs an impressive array of features into a compact design. With dual analog preamps, versatile EQ settings, and a variety of amp voices, it provides a rich tonal palette suitable for numerous styles. The standout digital reverb and effective cabinet simulations enhance its usability for both practice and performance. However, the lack of spring reverb emulation and subtlety in tube emulations may leave some tone purists wanting more. At $459, it’s a serious investment, but the functionality and quality make it a worthwhile addition for any serious guitarist.
