ReelBus 4 from ToneBoosters is a sophisticated tape recorder, tape flanger, and tape echo simulator plugin designed to bring authentic analog tape characteristics to digital audio production. It builds upon previous versions by incorporating advanced tape saturation models, creating rich, warm sounds through detailed emulation of tape compression, hysteresis, and spectral effects. The plugin also introduces a unique 'Drive-EQ' feature, enabling users to apply frequency-dependent tape saturation for more nuanced tonal shaping.

This plugin stands out with its separate controls for tape saturation, wow-and-flutter, tape wear, hiss, and asperity, delivering a highly customizable and realistic tape experience. ReelBus 4 also includes innovative effects such as a tape stop simulator, an all-new echo and flanger simulator, which enhance creative possibilities while maintaining the classic tape sound. These features allow producers and engineers to recreate vintage tape machine sounds with precision and flexibility.

ReelBus 4 offers a user-friendly, scalable, and themeable interface supporting high-resolution audio up to 384 kHz and immersive formats like Ambisonics and Dolby Atmos for up to 16 channels. It provides zipper-free automation and a wide dynamic range with virtually unlimited internal headroom. This makes the plugin suitable for modern production environments requiring both sonic authenticity and advanced technical performance.
