Hermansson 5 gain stages rebuild in a Marshall 1959HW 

I've used this brand new Marshall 1959HW as a donor for the Hermansson 5 gain stages rebuild. The whole preamp circuit is built on turret boards. It's an all-tube distortion circuit, no clipping diodes or transistors.
Other features:
• Tightness control
• Punch control
• 3-way preshape switch
• 3-way punch range switch
• 3-way presence range switch
• 3-way bright switch
• 3-way mid boost switch
• 3-way more mids/dark switch
• New ground layout and preamp shield
• LND150 based effects loop
I have the gain set to 2/10 in this clip.Guitar straight into the amp, TC D-two in the loop, cab is loaded with Greenbacks.
