This RR is an awesome little board! I have a nice fuzz pedal, HBE Germania Treble booster, (based on a rangemaster)... got a NOS germanium transistor and unbelievable tone. It is positive grounded tho, so I had to use batteries for it, until now!

I didn't want to modify the pedal, and put the RR inside so I made a lil box out of it... 1st output is 9V+pin for the fuzz and the other is a regulated 9V-pin to run a couple other effects down the line. :)
Plastic enclosures. I totally forgot about those. I have been using Altoid tins, but the enclosure you are using looks more professional.
Nice job!
