The Best Bass Preamp on the Market

At $749.99 the Mantle is not a casual purchase — and Walrus didn’t build it like one. This is a serious analog bass preamp and DI built around a pair of custom-wound Sapphire transformers (Neve-inspired input + API-inspired output) running on an internal +24V rail for massive headroom. The goal is simple: take whatever bass you plug in and give it a polished, harmonically rich, studio-ready foundation without burying it in options. What you actually get on the face of the pedal is refreshingly minimal: Gain (transformer-based, –6 dB to +23 dB) Bass and Treble (11-position rotary switches with carefully designed boost/cut behavior) Active/Passive pad Ground lift That’s it. No menus, no dual-function knobs, no feature bloat — just three main controls that let you shape the low end, add presence, and drive the transformers cleanly or with a bit of saturation. In this video we're running the Mantle with both passive and active basses, showing what the transformers actually do to the tone, how the EQ behaves in practical settings, and whether the high-end components and simple layout justify the premium price for real-world bass players. https://www.zzounds.com/a--3970972/it... ------------- Join The Bass Channel to get access to perks:    / @thebasschannel   ------------- Check out our complete Bass Cab IR collection here: https://www.thebasschannel.net ------------- We make a small commission on any product purchased through our affiliate links.
