Their marks are used solely to identify the equipment whose sound is simulated.
With the JS-8, you can use seven effects types simultaneously in a single effects patch, including AMP (amp modeling), FX
(various effects), EQ (equalizer), NS (noise suppressor), DELAY (delay), and REVERB (reverb).
For the FX type, you can select among compressor, distortion, wah, and a wide variety of other effects.
Internal Effects
AMP (amp modeling)
Models sounds passed through guitar and bass amps.
COSM modeling simulates not just preamp and speaker characteristics, but even miking as well.
You can select from a large number of different amp types.

FX (effects)
Provides a wide variety of effects to choose from, including compressor, distortion, wah, and many others.

EQ (equalizer)
Adjusts the volume levels for different frequencies in the low-frequency to high-frequency ranges.
Low and high midrange settings feature parametric equalization.
”EQ parameter list” (p. 28)
NS (noise suppressor)
This effect suppresses noise and hum from the guitar’s pickups.
Since the noise reduction follows the guitar sound’s envelope (the change in volume over time), it has
practically no influence on the guitar sound itself, thus producing a highly natural effect.

DLY (delay)
A delayed sound is added to the normal guitar sound, producing a thicker tone with a distinctive ambience.

CHO (chorus)
This effect adds a subtle frequency modulation, producing a beautiful sound with greater breadth and body.
”CHORUS parameter list” (p. 30)
REV (reverb)
This effect adds reverberation and other spatial effects.
Set the REVERB TYPE to choose from a variety of different types of reverb sound.
