Making of the Mantle - With Ian Martin Allison

Описание: Ian Martin Allison sits down with Matt Danner and Jason Stulce to talk about the making of the Mantle Analog Bass Preamp & DI.

In this interview, Ian shares his perspective as a working bassist, while Matt and Jason share deeper insights into the design philosophy, engineering choices, and problem solving that shaped the Mantle into a studio-grade bass preamp and DI.

The Mantle is a premium analog bass preamp and DI developed in close collaboration with Ian Martin Allison. Designed to provide an impeccable sonic foundation, it delivers the kind of depth, clarity, and authority bass players expect from high end studio gear, whether on stage, in the studio, or at home.

At the core of the Mantle are proprietary, custom-wound Sapphire transformers, crafted to deliver authoritative low end and forward mids inspired by classic Neve-style circuits, paired with an open, articulate top end influenced by revered API preamp designs.

Key Features:
• Studio-grade bass foundation
Custom-wound Sapphire transformers: authoritative lows, forward mids, open top end
Transformer-balanced XLR DI: huge headroom, uncompressed dynamics, full low-end response
Developed in collaboration with Ian Martin Allison
• Musical, intentional tone shaping
High-impedance JFET input buffer for touch sensitivity and clarity
Transformer-based gain (-9 dB to +18 dB): clean headroom to rich drive
Custom Bass and Treble EQ with selectable HPF/LPF shaping
• Rig-ready flexibility
1/4” in/out plus balanced XLR out for simultaneous amp and FOH/interface use
Active/Passive pad and Ground Lift for quieter, more compatible setups
