01Internal Pre FX Guv'nor (Drive Block)
Built-in Marshall Code Pre FX stomp used to tighten high-gain front end
The original tone relies on a scooped Mesa Mark IIC+ preamp driving Marshall EL34 power tubes. On the Marshall Code 25, pair the high-headroom American Clean preamp or JCM800 model with the internal Guv'nor overdrive set as a tight boost (low drive, high level) and pull the physical Mid control down to 3 while keeping Bass and Treble at 7 to recreate the iconic graphic EQ 'V' curve. Note that the physical faceplate on the Code 25 lacks a presence knob (presence is handled in the deeper preset menus as null/flat on the faceplate).
