removes noise during play pauses without affecting sound quality. The amp simulator recreates the
sound of various speaker cabinets.
ZNR/AMP (Type&Prm)
Selects ZNR sensitivity and amp simulator type at the same time.
ZNR (ZOOM Noise Reduction)

as high as possible without causing the sound to be cut off unnaturally.

back cabinet. The right-digit value controls ZNR sensitivity.
