PSP develops high quality audio effect and processor plug-ins. Our products garner rave reviews and endorsements from every corner of the music production, engineering, composition, and post-production worlds.  Our  plug-ins have become staples in professional and home studios worldwide.  Our credo explains our simple philosophy: It's The Sound That Counts!

The PSP SpringBox gives me the classic character of an outboard Spring Reverb unit with the incredible parameter control of a plugin. I've been messing around and using it on vocal busses, all sorts of synths and different EFX chains, and it's helping me find new sounds. Great plugin!
