PLATE AND SPRING REVERBS
Our Plate and Spring effects are simulations of two popular mechanically
constructible reverb units. The critical component in a real plate reverb
is large plate of sheet metal. Plate reverbs tend to have a high diffusion
rate, so for an accurate representation the DIFFUSE knob should be on
the high side.
The Spring Reverbs simulate the effect of broadcasting a signal into an
actual coiled metal spring. Spring reverbs are commonly found built into
many guitar amplifiers.
MODVERB
All of the reverbs have LFO modulation applied to the delay line lengths,
but ModVerb has delay lines nearly as long as the E-Dome delays and an
additional modulation in which the internal wiring of the reverb smoothly
changes at the LFO rate.
METAL BOX
This reverb type also has extra modulation. It replicates a very small
space, perhaps the size of a metal cargo-shipping container. It will give
a sort of chorused sound with very short reverb times and a lot of
modulation.
ECHO
This a basic delay algorithm, using all the same controls that the reverbs
use. The TIME knob sets the feedback amount, while the PRE-DELAY
sets the echo time. Add some diffusion to create more interesting delay
effects.
