Mesa Dual Rectifier Multi-Watt - Hermansson Amplification

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.

[@guidedbyechoes]

When you do your changes do you make mods to improve the amp, or do you basically redesign the amp from the ground up? Because your designs clean up so well most people could do entire gigs with one channel and a volume knob.

I install my own preamp designs in the amps I rebuild. I always need to change some internal layout in the amps and install circuits above the PCB, install shielded cables etc.
So I use the amps as platforms for my own circuit designs.

What are these guitar cables you are always using?

[@HermanssonAmplification]

I make these cables for my personal use, silver plated cables with super low capacitance, FEP jackets, rated at 200C° and 900V RMS. So you can say it’s more of a laboratory cable than a normal guitar cable 🤓

[@haiderman1610]

Which guitar are you using here?

[@HermanssonAmplification]

Hagström Swede, made in Älvdalen, Sweden 1975.

[@lookformeinthewaves]

I’ll take the one on the bottom 😂

A Rev F with Hermansson 4 gain stages circuit 🤓

I have three Mesa Dual Recs, and nice amps they truly are. But any Marshall JCM 2000 DSR will blow them out the water. Even the new Chinese Marshall DSRs will blow the Mesa away.
