GigaVerb has 20 Parameters, that give exceptional soundfield and tonal shaping control over
reverberation. It is best suited for simulating natural room environments that have no acoustic
treatment, like churches and assembly halls. A one input/four output GigaVerb Module, is capa-
ble of producing reverberation of virtually any size, shape, depth, timbre or soundfield location.
Bigverb is a slightly trimmed version of the GigaVerb, offering much of the same flexibility and
controls as GigaVerb, but using less memory. Bigverb lets you produce a high-quality reverb,
while including one or two other small Modules in the Algorithm.
Like Bigverb, MFX Reverb is a slimmer and trimmer version of GigaVerb, but MFX Reverb is
specifically designed to fit efficiently into Algorithms, using multiple effects Modules.
Also available, are true stereo reverbs: Stereo GigaVerb and Stereo Bigverb. These Modules
allow channel inputs to remain totally discrete, thereby retaining the imaging of stereo input
sources. These reverbs also offer stereo mix controls that allow mixing of left- and right-channel
early reflections and reverberations. These controls can be used to blur stereo imaging of input
sources, creating a subtle stereo ambience rather than fully discrete reverberation channels.
Before covering all the reverb Parameters and their definitions in detail, let's discuss the benefits
and theory behind reverberation.
Reverberation, or room ambience, occurs when acoustic energy is reflected off room surfaces,
materials, and objects. Using reverberation with your guitar gives the listener a sense that the
material is being performed in an environment where you are not actually present.
The GSP-2101 Artist uses early reflections in several Modules to get a better emulation of the
natural sound of a room. Early reflections are short clusters of direct reflections from the room's
closest walls. In an average size room, these direct reflections usually occur within the first 30 to
100 milliseconds, depending on the size of the room and the placement of the sound source
within the room. Adding these early reflections to the reverberation increases the perceived
reverberation time and the apparent size of the reverberant space. Adding more than small
amounts tends to make the reverb sound unnatural.
