Hi,
    this is my first post in this forum and i find this forum really very interesting!
    I have a Marshall MG15CD and and i'm interested to do some tweaks in it.
    I want  some improvements in the overdrive section.Like a mod of increasing its gain. The clipping happens because of 2 LEDs (Red and Green) . Can the gain be increased by using 1N4148s or 1N914s instead of the LED's ??
If yes, then what are the other changes that i need to do??

Help is appreciated

Thanks and Regards
