Available for download, PSPAudioWare PSP SpringBox is a reverb plug-in for production and pro-audio mixing purposes. This software models the sound of a hardware spring reverberator, the sort often found in vintage guitar amplifiers.

PSPAudioWare has gone to great lengths to emulate a spring tank faithfully, giving you the sound one associates with spring reverb. The plug-in lets you select between two independently configurable virtual spring channels, each with Time, Trim, Presence, Damp, and high-pass filtering controls. You’ll also note stereo spread, diffusion, and pan over both channels.

This software is compatible with Mac and Windows platforms. It will operate in AU, VST, AAX, and RTAS formats. An iLok account and the iLok License Manager application are required for operating this software, though the iLok dongle itself is not required.
