Something truly special just for bassists, we've got the high-fidelity, all-analog experience of the Walrus Audio Mantle Analog Bass Preamp and DI. The Mantle, a marvelous design straight from Walrus and bassist Ian Martin Allison, punches in with a pristine preamp design for bass guitars in particular. Proprietary components, a truly seamless playing experience, and easy connectivity all compound to elevate the Mantle to truly righteous levels.

Everything in the Mantle Preamp starts with a special ingredient. At the heart of this preamp is a set of proprietary, custom-wound Sapphire transformers – designed and crafted by Walrus Audio. These high-quality, high-fidelity components are designed to be reminiscent of Neve consoles with their focus on formidable low-end and midrange force paired with an airy and articulate top end that hearkens to coveted API preamps. Totally, this customized design puts forward a tonal profile that is simple, classic, effortless, and primed for the stage or studio.

The Mantle Preamp is designed to be unencumbered and unambiguous in its operation. Centrally, the Mantle calls upon a single Gain control and a two-band EQ section with precisely delineated values to get your sound down to a science. Walrus went ahead with this pedal to focus on a more vivid EQ shaping experience that offers more than your average EQ frequency shelves. In addition, the precision offered by numerically-valued positions on the EQ and gain sweeps make the Mantle an excellent pedal for getting tonally exactly where you want and replicating such results when settings are changed. The Mantle's transformer-based gain structure spans between -6dB to +23dB.

Meant for the highest fidelity and most seamless integration on the stage or in the studio, the Mantle comes fitted with a number of additional playability and connectivity features. For one, an active/passive pad introduces a -10dB input pad meant for use with active pickup basses or instruments with existing high-output preamps for preventing overloads in the input stage. For another, the Mantle features a balanced XLR output for use in DI out situations. This XLR out can be used simultaneously with the pedal's 1/4" instrument out for parallel output in recording or performance scenarios.

A preeminent preamp for bassists, the Mantle is a heaven-sent for any and every setup, style, and sound. Take it up, make your mark.
