I would like to do that to a Ibanez Tube Screamer. I used Google to translate the page but it's not very accurate. I really want to attempt that proccess but I'm not sure of what exactly needs to be done.
Somebody could make money off of this, just like how people make money off of modding pedals.
The Super Distortion & feedbacker DF-2 is the early, rare version. Any metal polishing or plating company could polish a pedal case for you for a reasonable price.
