Mesa Triple Rectifier Rev G rebuilt with Hermansson 4 gain stages circuit.
Both channels have a lot more distortion available, lower noise floor, better dynamic response, and a more musical EQ. I've installed my tightness control for both channels. Extra features for this amp are 3-way bright switch (both channels), 3 way tight switch (both channels), 3-way mid boost/gain boost switch (global) and 3-way more mids switch (global).

Guitar straight into the amp, running through a Malmberg 4x12 with old greenbacks.

MARSHALLS!
I've started doing Marshall rebuilds again and found out it was a long time ago I posted any pictures from any Marshall rebuild projects.

It's mostly the 5 gain stages rebuild (with the red turret board) but some pictures of the 3 gain stages rebuild as well.

This Mesa Triple 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 has better string separation and dynamic response.

Extra features for this amp are 3-way bright switches (orange + red + green channels), 3-way tight switches (orange + red channels), 3-way mid boost/gain boost switch (global for orange and red channels), 3-way more mids switch (global for orange and red channels), and a 3-way mid boost switch for the push mode (green channel).

If you happen to be near Dala-Järna on Saturday you will have the opportunity to hear some Hermansson amps live when I'm playing with my band Benesser. We will play down by the river where MBN.se will set up a stage for us. Really looking forward to playing live in my home town again!

It’s finally time for a gig at Kämpudden in Dala-Järna again. It was five years ago, but on Saturday, July 27 at 7 p.m. we’re happy to be back. Hope to see you there.

We also have the pleasure to announce that we are doing the concert in collaboration with the event company MBN.se, who will contribute with lights and build a large stage down by the river Västerdalälven.

Just had Fredrik Thordendal's Mesa Dual Rectifier back in for some updates and installment of six voicing switches. I rebuilt this amp for Fredrik and installed the Hermansson 4 gain stages circuit in 2022. The amp also has my tightness controls and the new extra features are 3-way bright switch (both channels), 3-way tight switch (both channels), 3-way mid boost/gain boost switch (global) and 3-way more mids switch (global).

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 control for the orange channel so the voicing follows the gain sweep while the red channel is made slightly looser for lead stuff. The green 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, the push mode also have better string separation and dynamic response.

I've rebuilt both channels of this amp, the distortion channel has the Hermansson 4 gain stages circuit + my tightness control. The clean channel is more open-sounding and extra crispy on the top.
Both channels have a lot more distortion available, lower noise floor, better dynamic response, and a more musical EQ.

Extra features for this amp:
• Tight-switch for the red channel
• Mid boost-switch for both channels
• Bright switch for both channels
• Loop changed to serial
