About this plugin
AudioThing's Mantis faithfully emulates the Carlsbro Mantis, a rare 1970s bucket-brigade delay unit, capturing the warm, organically degraded character that made BBD-based echo units distinct from their tape and solid-state counterparts. The plugin models eight TDA1022 chips, each offering 512 stages of analog signal delay passed through a chain of capacitors - the fundamental mechanism that gives BBD delays their compressed high-end and natural compression characteristics.
The core feature set includes four independently selectable delay taps with swell controls, allowing for complex rhythmic echo patterns, plus a rotafaze modulation section that can either simulate tape wow and flutter or function as a subtle chorus-delay hybrid. Two operational modes address the original hardware's limitations: "Vintage" restricts the base delay to 0.512ms through 51.2ms, accurately reflecting the fixed-delay architecture and frequency response shifts that darkened longer delays and brightened shorter ones. "Modern" mode extends delay time to one second with host tempo synchronization, granting practical flexibility without sacrificing the core sonic character.

The Mantis suits producers and engineers seeking authentic analog warmth and character rather than pristine digital precision. It excels on drums, guitars, and vocals where the inherent noise floor and frequency-dependent coloration become compositional assets rather than liabilities. Among comparable BBD emulations, the Mantis distinguishes itself through accurate multi-tap architecture and the rotafaze section's genuine utility. For those prioritizing period-correct tone over DSP efficiency, it represents a convincing recreation of a genuinely obscure and sonically specific device.
