This Mesa Dual Rectifier is modified by Hermansson Amplification. The red and orange channels have the Hermansson 4 gain stages circuit.
The distortion is tighter, the dynamic response is increased and the overall noise floor is reduced. The layout is changed and shielded cables are installed to improve the signal-to-noise ratio. I've integrated my tightness control with the gain controls for the orange and red channels so the voicing follows the gain sweep. The clean channel is changed to sound more open and the layout is changed for this channel as well so you can turn treble and gain all the up in push mode without oscillations, it also has more gain available.
Guitar straight into the amp, TC D-two in the loop.
