The CMOS Over Drive produces the same type of soft, "musical" distortion that is created when a tube amplifier is overdriven.
The input signal first passes through a compressor circuit, and is then fed to a CMOS amplifier, an EQ circuit for tonal variation, and a level control circuit.
The CMOS Over Drive produces a superb overdrive effect without destroying the delicate picking and expressive nuances of the original sound. Further, 2 equalizer circuits are used to maintain exceptional clarity in the high frequency range without producing a hard, "edge" sound. The inclusion of a compressor circuit achieves long sustain, making this a most versatile overdrive unit.
