Description

Edit description

Introducing the DSM Humboldt Electronics Simplifier mk2 Zero-watt Stereo Amplifier, a significant leap forward in the realm of analog amp simulation. This state-of-the-art pedal for electric guitar excels in delivering authentic tones and enhanced realism. Its fully analog construction ensures superior touch sensitivity and dynamic response, keeping your sound grounded and honest.

The Simplifier mk2 comes with a comprehensive set of controls to fine-tune your sound. These include a stereo speaker color control, a pre-amp voicing switch, and a spread on/off switch. The power amp clip and LED on indicator add to its user-friendly design.

The Simplifier mk2 is more than just an upgrade—it's a revolution in sound. With its redesigned preamps, it offers wider gain options and more accurate historic behavior.

The MS Brit offers a high level of gain, akin to a hot-rodded Marshall Plexi.
