I've built at Hudson Broadcast from layout 2 (without the chargepump) and I have run into problems.
The bypass works and I have sound coming through the pedal, but the output is very low. Both the gain switch and gain trim work. I can't really tell if the low cut works. This may be related to the low output.
So far I have scored the board and gone through all the component placements. I've found two mistakes the bottom 10u cap is off by one column, but I can't really see that that should make any difference. Also I was stupid enough to cut the 9 volt power row in order to fit the transformer, but thats been repaired.
