DSM Humboldt Simplifier MK II 2

The DSM & Humboldt Simplifier MK-II is a fully analog preamp, power amp, and cabinet simulation platform designed to deliver realistic amp response—without the need for external gear. With independent preamp voicings, analog power amp simulation with selectable tube characteristics, and dual cab simulation, it gives you precise control over every stage of your signal chain.

True stereo operation, dual FX loops, balanced XLR outputs, and headphone monitoring make it equally at home in direct recording, live performance, and silent practice setups. With zero latency and a no-menu interface, every adjustment is immediate and tactile—offering detailed tone shaping with the reliability of an all-analog rig.

SIMPLIFIER MK-II

The state-of-the-art in analog amp simulation.

The MK-II pushes analog amp simulation further—expanding tonal flexibility while preserving the immediacy, dynamics, and feel only analog circuits can deliver. All of this comes in the same ultra-compact footprint.

A CONTINUOUS QUEST

Since the release of the original Simplifier in 2019, the platform has remained a benchmark for analog amp simulation. The MK-II builds on that foundation—refining the core sound while expanding control and usability, without compromising the feel that set it apart.

WHAT’S NEW

Expanded Preamp Section
Redesigned preamps with increased gain range and improved response, offering greater flexibility across clean, edge-of-breakup, and driven tones.

Master Section Control
Dedicated master volume allows independent control of preamp and power amp drive, maintaining clarity while avoiding unwanted FX loop distortion.

Enhanced Power Amp Simulation
A dedicated power amp drive control lets you dial in compression and saturation characteristic of a pushed tube amp—unlocking a more realistic “sweet spot” feel.

Redesigned Stereo Cab Simulation
Reworked cab simulation based on extensive speaker response analysis. Replaces mic positioning with an intuitive three-profile speaker voicing system for faster, more musical adjustments.

Built-In Reverb
Integrated side-chained digital plate reverb adds space and depth without interfering with your core tone—one of the most requested additions from original Simplifier users.
