chorus pedal mod ideas???

[mars2010]

hello, i have a johnson sc-2 stereo chorus pedal i'd like to experiment with. this would be my first pedal mod, so if you can give me some tips/ideas i'd appreciate it. i've looked at some other chorus pedal circut boards and see similiar parts, but i can't find a schematic for this pedal yet. i do have good pics of the circut board for reference. the pedal has a decent chorus sound, but i'd like to see what i can do to it/learn from it. if it turns out good i'll rebox it and use. but if not, it can be a start for pedal parts. thanks.
