My third rebuild of a Marshall JCM900 SL-X. This one was modded before and upgraded with Mullard mustard caps.
Here it is before my modification.
Here are the parts I took out of this amp.
Here it is after my modification.
The whole preamp circuit is revoiced and changed to get a tight and focused distortion that is very dynamic and versatile.
You can play anything from metal, classic rock, broken up cleans and crisp clean just turning the two gain controls.
The power amp is also revoiced and got a punch control which gives you great control over the bottom end.
The power supply got some new electrolytic caps with higher voltage and temperature specs as well.
Guitar: Greco EGF1000 / Hagström Swede, straight into the amp.
TC G-major II in the loop for some delays.
Cab: Malmberg 4x12 with old Greenbacks.
Mics: Golden Age R1 mkIII, Tascam DR-40
I've revoiced this amp to be a dynamic metal monster I've installed a choke as well.
