The ultimate pedalboard amp.

DSM & Humboldt's beloved Simplifier just got a significant upgrade!

The Simplifier mk2 features redesigned preamps, a new Power Amp Drive control, Speaker type knob, Reverb, and a wider gain range.

The onboard Plexi, Blackface and AC30 preamps are even more dynamic, and capable of delivering beautiful edge-of-breakup tones!

The mk2's dedicated Power Amp Drive offers even more fine-tuning, with an upgraded Power Type switch and linear through Drive knob.

Next, a redesigned Cabsim section replaces the Mic position control for a knob that sweeps between 3 speaker profiles.

These can be adjusted for Combo, Twin or Stack voicings.

Best of all, DSM Humboldt made sure to include a Plate Reverb for the perfect amount of room control in your setup!

If you're looking to venture into silent stage rigs or need a compact amp solution, the Simplifier mk2 is a must-have.

A trio of redesigned preamp engines!

The Simplifier mk2 hosts 3 separate preamp options and a 3-band EQ to ensure top-notch voicing in any scenario.

• AC Brit : A sweet, sparkling voicing based on the AC30, known for its twinkling cleans and emotive verge-of-breakup grind.

• American : Supplies the quacky midrange and chunky bass of a 1960s Fender. Sweet when clean, roars when pushed!

• MS Brit : Packs on the glassy gain and forward character of a vintage Plexi stack.


Enhanced stereo cab sim control.

The Simplifier mk2's Combo, Twin, and Stack cab simulation controls are an excellent way to add a tight boost to your signal.

The MIC position control has been replaced with a Speaker control based on the V30, Blue Alnico, and Greenback.

Additionally, 3 separate classic cab types are available in Combo, Twin, and Stack configurations, so you're ready to hit any venue!

Built-in reverb.

Fans asked, and DSM Humboldt delivered!

A dedicated reverb knob provides crisp side-chained plate reverb to add width to your tone.
