AGX™ (Automatic Gain Expander)
Rocktron's patented AGX™ system solves the long standing problem encountered by guitar players
when using high gain distortion. The AGX™ circuit expands the gain of the amplification circuit only when
required based on the input level. When no signal is present, the AGX™ circuit expands down the amplifi-
cation level to a point where hum and noise are dramatically reduced.
