With its completely analog design, great care was also taken with amPlug's gain circuitry. The 'AC30' uses two natural-sounding gain stages to reproduce the distinctive AC30 tone. Even the circuit response of the original amp is simulated completely. The simulation extends not only to the response of the tone circuits, but also to the way in which the high frequency and gain are affected when you turn down the volume control of the guitar. Every detail has been faithfully reproduced.
