Shape
This control helps give a sense of both room shape and room size. Low values for Shape keep the majority
of sound energy in the early part of the reverb tail. High values move the energy to later in the reverb, and are
helpful in creating the sense of a strong rear wall or “backslap.
Boing
This is a unique parameter to the Spring reverb, designed to increase or decrease the amount of spring rattle
that is a physical characteristic of spring tank reverbs.
DELAYS
Delays repeat a sound a short time after it first occurs. Delay becomes echo when the output is fed back into
the input (feedback). This turns a single repeat into a series of repeats, each a little softer than the last.
Studio Delay
The Studio Delay features up to 2.5 seconds of stereo delay and offers a built-in ducker that attenuates the
delay output whenever signal is present at the input. This can be used to keep the original signal from being
muddied up by delay repeats.
Digital Delay
The Digital Delay is the cleanest, most accurate of the delay programs, with up to 5 seconds of mono delay
and the built-in ducking feature.
Tape Delay
In the days before digital, delays were created using a special tape recorder in which the magnetic recording
tape was looped, with closely-spaced recording and playback heads. The delay effect was created by the
tape moving in the space between the record and playback heads – while delay time was adjusted by
changing the speed of the tape loop. Although very musical-sounding, wow and flutter combined with a
significant loss of high frequencies, and to some extent also low frequencies, are all elements commonly
associated with tape recordings. The Tape Delay offers up to 5 seconds of mono delay.
Pong Delay
This delay effect pans the delay repeats from left to right, while the input signal remains at its original
(center) position. Pong Delay offers up to 5 seconds of mono delay time.
Modulated Delay
The Modulated Delay is enhanced by an LFO (low frequency oscillator) that produces a chorusing effect on
the delay repeats. This is a great delay for guitar and instrument passages that need that “special some-
thing.” The Modulated Delay features up to 2.5 seconds of stereo modulated delay.
Reverse Delay
This delay effect emulates the old studio trick of flipping a tape over, playing it backwards through a tape
delay, and recording the effect. The delays “build up” from softer to louder – creating the sensation that the
delays come before the signal. Up to 5 seconds of mono delay time are available.
DELAY CONTROLS
Time Range
Controls the length of the delay relative to Tap Tempo. At the 12 o’clock position, delay repeats are synchro-
nous with the Tempo light (represented by a Quarter Note); lower values create faster repeats, higher values
