{"type":"firestarter.listing","listing":{"id":"lst_CW0c3ML4","product_name":"Mantle Analog Bass Preamp // D.I.","category":null,"description":"*Whoa this is popular!  New orders shipping mid September*\n \nPlease Note: The Finch Power Supply does not power the Mantle.\n\n\nThe Mantle is a premium preamp and DI for electric bass, created in close collaboration with Ian Martin Allison. Designed to give your instrument an impeccable sonic foundation, the Mantle brings studio-grade refinement to any environment - whether you’re stepping onstage, tracking in the studio, or shaping your tone at home. \n\n\n\nAt the heart of the circuit are our proprietary, custom-wound Sapphire Transformers, engineered to deliver the authoritative low-end and midrange push reminiscent of a classic Neve circuit, paired with an airy, articulate top end inspired by revered API preamp architecture. Together, they provide a harmonically rich canvas that elevates your playing while preserving every nuance of your instrument. \n\n\nThe Mantle empowers you to sculpt your signal with intention, offering musical gain, smartly tuned EQ, tremendous headroom, and transformer-balanced outputs. Every component and stage of the signal path is built to ensure whatever comes next - amp, interface, or mixer - receives your bass in its most confident, fully realized form. \n\n\n“I am an absolute DI fanatic, owning probably 50+ DIs and preamps. And while they’re all great in specific ways, they all either lack something critical or try to stuff in too many features, making for an underwhelming or even overwhelming user experience! This is exactly why I wanted to make Mantle. I needed this product to exist. I’m thrilled to say that now it does. And it is absolutely killer.”  \n\n\n                                                                                                                   -Ian Martin Allison\n\n\n Features \n\n\n\n\n\nHigh-impedance JFET Input Buffer for articulate, touch-sensitive response and exceptional clarity. \n\n\nUp to +23dB of transformer-based gain offering clean, magnetic, harmonically rich amplification with premium depth and detail. \n\n\nCustom-ta","images":["https://cdn.shopify.com/s/files/1/0906/8480/files/Mantle_front.jpg?v=1765470491","https://cdn.shopify.com/s/files/1/0906/8480/files/Mantle_left.jpg?v=1765470667","https://cdn.shopify.com/s/files/1/0906/8480/files/Mantle_right.jpg?v=1765470667","https://cdn.shopify.com/s/files/1/0906/8480/files/Mantle_back.jpg?v=1765470511","https://cdn.shopify.com/s/files/1/0906/8480/files/Mantle_input-jacks.jpg?v=1765470527","https://cdn.shopify.com/s/files/1/0906/8480/files/Mantle_output-jacks.jpg?v=1765470534"],"price":749.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:57:20.323Z"},"share_url":"https://firestarter.network/l/lst_CW0c3ML4","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
