Hi WitSok,
I can't tello you the impressions before the mods, because I only kept the guitar "mint" for a few days, then I modded it and a year and a half passed since. I couldn't really stand that loose tone pot!
Anyway the "bright" switch works like a charm, I use it when I connect to a "dark" amp or for rhythm with overdrives, it really helps to "demud" the sound.
The rest of the mods I think are more a matter of personal taste than anything else, I really prefer black pot covers on this guitar (next time I'll open it I think I'll also swap the dpdt chrome switches with black ones).
Anyway I posted about the next mods I'm willing to do on hte Fallout here:
