BPB Dirty Spring is a free spring reverb effect designed to add classic spring reverb character to your audio productions. It offers adjustable controls including pre-delay, decay, and tone, allowing you to shape the reverb tail to fit your mix perfectly. The plugin features a Mix knob to blend the wet signal with the dry, giving you precise control over the effect's presence.

A unique aspect of BPB Dirty Spring is its built-in bitcrusher effect, which adds digital grit and texture to the reverb. The Dirt knob lets you dial in the amount of bitcrushing, with six preset options ranging from subtle warmth to intense distortion. Additionally, the Kick button simulates the classic sound of physically kicking a hardware spring reverb, providing an authentic vintage vibe.

This plugin is compatible with both Windows and macOS systems and supports a wide range of plugin formats including VST2, VST3, AU, and AAX. It works in both 32-bit and 64-bit digital audio workstations, making it accessible to a broad range of users. As a free tool, BPB Dirty Spring is an excellent choice for producers seeking a distinctive reverb effect with added sonic character.
