The PSA1000 Analog Saturation Unit plugin is a faithful modern recreation of a renowned '90s analog guitar preamp, widely respected in recording studios worldwide. This plugin captures the unique tonal characteristics of the original hardware, delivering warm, rich saturation that enhances a broad range of instruments. While originally designed for guitars, its distinct sound is equally effective on electric pianos, organs, synthesizers, and electric basses, making it a valuable tool for diverse musical applications.

Beyond instrument tracking, the PSA1000 plugin has earned a place in the mixing stage, where it adds character and depth to drum rooms, percussion, vocals, kicks, snares, and sound effects. The development process involved careful circuit modeling and fine-tuning by ear to ensure authentic analog behavior and sonic richness. This attention to detail preserves the essence of the original unit while offering enhanced control and flexibility for contemporary music production.

Nembrini Audio has introduced modern features to the PSA1000 plugin, including independent controls for left and right channels with options for individual and linked adjustments. Users can shape the stereo image with mid/side processing, a stereo spread circuit, and an analog link circuit that simulates natural channel differences. Additional controls like dry/wet mix, phase reverse, and input/output level knobs provide extensive creative possibilities. The package also includes a streamlined PSA1000 Jr version, featuring the same distortion algorithm in a simplified interface, enabling producers and engineers to harness the plugin’s full potential.
