SUS4 Crimson

Transformer-style preamp drive. Add iron, harmonics and weight to anything you run through it.

Included in the SUS4 plugin bundle. One licence, every plugin, every update.

Transformer-style preamp drive: iron, harmonics and weight added to anything you run through it. From a whisper of saturation to full front-end attitude.

Great on flat DIs, thin samples and sterile sources that need a hardware front end they never went through.
