(Foreword: excuse my limited knowledge of english language and writing)
These simple mods (removing one resistor and one capacitor + adding one or two resistors + shorting one pot) are for those who are not satisfied with dirty channel sound and want it to be more alive.
First: short input and output of the gain pot on channel 2.
Second (for those who don't like punch-off mode on channel 2): unsolder one leg of R88 resistor (100k), unsolder one leg of condenser C20 (10microfarads) or remove it completely.
Third (for those who think that reverb and echo effects are too low in the mix with dirty channel (channel 2): add 100k resistor (or 100k-250k trimmer pot) in parallel with R60 (47k).
Fourth: (for those who think that crunch mode is too loud on clean channel - channel 1) add 47k resistor in paralel with R30 (47k).
I'll add 4 pictures.
