A versatile preamp pedal for the modern bassist

The Simplifier Bass Master from DSM & Humboldt is a compact yet powerful preamp pedal designed specifically for electric bass. It combines classic tonal foundations with modern flexibility, making it equally suited for stage, studio, or a home pedalboard setup.

The pedal features three distinctive preamp modes – Clean, Comp, and Hot – covering a wide range of bass tones, from transparent and articulate to warm and driven. A parallel signal path, adjustable with onboard EQ and filters, offers further control and allows you to blend clean and processed signals without sacrificing low-end or clarity.

Bass Master also includes realistic cabinet simulations, dual DI outputs, flexible FX loops, and a headphone out – all packed into a rugged format optimized for today’s mobile and digital workflows. Whether you're gigging without an amp or building a complete rig in pedal form, the Bass Master provides a reliable foundation for your sound.
