TS-999 SubScreamer is a digital overdrive pedal emulation designed to replicate the sound and feel of its original hardware counterpart created for Subhuman guitarists Matteo Buti and Elia Murgia. This pedal draws inspiration from the legendary green '808' overdrive, enhancing it with features that allow users to add grit and clarity to clean guitar tones or tighten amplifier distortion. It excels at delivering a focused sound that avoids muddiness in the low-end and fizz in the high frequencies, making it suitable for a wide range of guitar styles.

The development of TS-999 involved detailed modeling of every component in the original analog circuit to faithfully reproduce its sonic characteristics. This includes emulation of input and output buffers, diode clipping circuits, and op-amp saturation, all crafted to ensure real-time responsiveness and playability with efficient CPU usage. The pedal supports multiple clipping modes and bass response settings, providing control over the tone's character and dynamics.

TS-999 is designed for use in live performance, recording, and mixing environments within hosts that support VST or AU plug-ins. It offers features such as mono and stereo processing, selectable oversampling rates, and fully automatable controls with zero latency. These capabilities make it a powerful tool for musicians seeking authentic overdrive tones with flexible integration into digital audio workstations.
