Mesa Triple rectifier - pre multi-watt - Hermansson 4 gain stages circuit 

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. The green channel is changed to sound more open and the layout is changed for this channel as well, the push mode have better string separation and dynamic response.
Extra features for this amp are 2-way bright switches (orange + red channels), 2-way tight switches (orange + red channels), and a 2-way mid switch (global for orange and red channels).
Guitar straight into the amp.
